Install Packages (for dummies) - package

I know there's a lot of information on here about installing python packages, but I'm quite new to python and I think I need a more "for dummies" level of help.
I was trying to install openpyxl for which as far as I can tell I need easy_install, for which, as far as I can tell, I need setuptools. I tried running the code provided here https://pypi.python.org/pypi/setuptools which is supposed to download and install setuptools (and according to some sites, easy_install aswell?) - it runs successfully, but help(modules) doesn't show setuptools or easy_install as modules, I have no idea whats installed and what isn't, or how I'm supposed to install any of it!
Essentially I'm very confused, very frustrated and really need someone to talk me through (in idiot-speak) what I'm supposed to do.
Thankyou!

We all start somewhere, I was there two weeks ago.
I'll assume you're using Python2. I believe Distribute and Pip are recommended for Python3 (which I will be using as examples). I will also assume you are on Windows.
First, python needs to be registered to Path. To check if this has been done automatically, open a command prompt (start -> programs -> accessories), and type 'python', then enter. If it returns the version number, etc, skip down a bit. If it throws an error, you need to add Python to Path.
Adding Python to Path
To add Python to Path on a Windows computer, go to:
Control Panel -> System -> Advanced Settings -> Environment Settings -> System Variables
Scroll down to select path, then click edit. Copy the entire line to a text document, and add your install directory for Python.exe (and the scripts folder) using ';' as a delimiter between different directories. Copy this back to Path and save. (Additionally close your command prompt window to reset it.)
For my Windows 7 machine, I added:
;C:\Python33;C:\Python33\scripts;
Take care when editing this file. There are many videos out there describing this in detail if you feel unsure about changing this.
Installing Modules (Such as setup_tools)
Once Python is registered in the Path file, download and unzip setup_tools to a folder within your Python install directory called 'modules'. I use ExtractNow to unzip, as it will unzip twice (as required) automatically.
Open a command prompt window again, and direct it to change directories by typing
cd [directory for module you want to install]
On my computer, this would be
cd C:\Python33\modules\distribute-0.6.40
Again, I use distribute, rather than setup_tools as it sounds like you need would for Python2. Simply use the appropriate directory. Press enter to change the directory.
Once you've entered this and it shows a changed directory, type:
python setup.py install
This indicates that you want to use the program python to use the setup.py file in the specified folder to install the module. This should be successful, and will write many lines of code.
If you want to install other modules, you would install them in a similar way. Python would automatically use setup_tools on your computer to finish each install.
Remember to import at the start of your script when using them to code:
import [module]
Happy Programming!

How to manually install packages for MikTex

I am using MikTex 2.9 and Texmaker. I need to download packages, such as the sespace package, manually from https://ctan.org/. I have done that and placed the resulting folder in: C:\Users\User1\AppData\Local\Programs\MiKTeX 2.9\tex\latex
Other previously installed packages are in that location and are recognised by MikTex as present.
The setspace folder contains setspace.sty and two test files. However when I compile in Texmaker it doesn't recognise that the package is present, and wants to download it.
Does the .sty file need to go somewhere specific, and how do I find out where that might be, please?

Trying to set up a deployment package for silent uninstall of Notepad++ and installation of a new version

All of the below on Windows 7 Machines and regarding Notepad++ installation / uninstallation:
Uninstaller
When I try to uninstall using the command
if exist "C:\Program Files (x86)\Notepad++\uninstall.exe" "C:\Program Files (x86)\Notepad++\uninstall.exe" /S
there are some files left in the Notepad++ file afterward. Notepad++'s uninstaller, when run manually, prompts halfway through the uninstall asking "Do you want to keep your custom settings" and I'm thinking that the command may be choosing to answer this "Yes" by default. I'm wondering if there's an easy way to have it choose "No" here instead. If not, I can probably just delete the folder.
Installer
I'm running the installation using the 32 bit default .exe file from Notepad++ in a deployment package compiled in Lansweeper. What I'm noticing is that presently, the package executed the CMD uninstall command, but stops short of installing the new version. For reference, I've been using an installed 7.3.2 and the installer for 7.3.3 to test, so that it should uninstall the 7.3.2 and install 7.3.3 by the end of the package.
I'm wondering if the fact that there are a number of options in the Notepad++ installer could be the culprit here. If it is better to install via command line or to include some sort of configuration file I'm fine with either option, just not especially well-versed in doing them.
Notepad++ Installer requests the following during installation:
Select a language - should choose English
Choose Components - want to be able to customize selection of localization / auto complete / themes / context menu / plugins / auto update according to our requirements
Choose Components - Don't use Appdata, Allow Plugins to be loaded from Appdata, and Create Shortcut on Desktop should all remain unchecked
Run Notepad ++ - should be unchecked (checked by default)
All the other components that I can see are straightforward Next / I Agree buttons.
I'm hoping someone may be able to make helpful suggestions here as I've not had any experience with configuring silent installs with specific parameters. Notepad++ doesn't seem to have its own MSI and I won't use a third party one so some sort of batch or configuration file or flagging options in cmd if possible are the preferable options.
Please let me know if there's any additional information I can provide that may be helpful.
Thank you in advance.
If you just need to update to the latest version. It is quite simple. Run the newest installer again and it will automatically update older versions.

Silent Install Notepad++
I'm using the command:
start /wait npp.7.2.Installer.x64.exe /S
Didn't show any interface during silent installation.
Notepad kicks a secondary process that doesn't finish until success is evaluated.
try:
"%ProgramFiles(x86)%\Notepad++\uninstall.exe" /S

What are dronekit-python dependencies?

The dronekit Getting Started page suggests installing WinPython to use dronekit-Python on Windows because it includes the dependencies. I already have a working Python installation and I prefer not to risk messing it up with WinPython. What are the dependencies I need to install?
As of DKPY 2.0 this is outdated. Also, I might move to making a MavProxy module depending on whether or not the unpaid devs decide to stay when 3DR stops funding Dronekit
I've written a procedure to help with this problem which I've pasted. 3DR claims they're going to fix it, but in the mean time I hope this will help.
This setup is for Windows 64-bit systems only, although similar procedures will work with 32-bit.
Install MAVProxy and run it once before reaching step 5.
Install Notepad++.
Install Python v2.7.
Inside the Python folder, run WinPython Control Panel and select Advanced->Register Python.
Inside the same folder, run WinPython Command Prompt and input the following four commands:
• pip uninstall python-dateutil
• pip install droneapi
• pip install console
• echo module load droneapi.module.api >> %HOMEPATH%\AppData\Local\MAVProxy\mavinit.scr
Install WX Python. It should be the 64-bit Python 2.7 version.
Download and install OpenCV 2.4.11 to any folder
• Copy/paste the file cv2.pyd from OpenCV\build\python\2.7\x64\ to \python-2.7.6.amd64\Lib\site-packages.
Steps 8 through 11 apply to SITL only
Follow the online documentation for setting up Cygwin for SITL in Windows
Go to C:\cygwin\home\Your Username\ardupilot\Tools\autotest\
Open sim_vehicle.sh in Notepad++
• Change line 429 from…
cygstart -w "/cygdrive/c/Program Files (x86)/MAVProxy/mavproxy.exe" $options --cmd="$extra_cmd" $*
to...
cygstart -w "/cygdrive/c/Users/YOUR USERNAME HERE/Desktop/WinPython-64bit-2.7.6.4/python-2.7.6.amd64/Dronekit/Scripts/mavproxy.py" $options --cmd="$extra_cmd" $*
Note: This location changes depending on where you installed WinPython. For me, it was the desktop.
Start simulations as you would normally for SITL. To run Python scripts during the simulations, use the command
• api start Path to script\script_name
To use the code to connect to an actual copter, open WinPython Command Prompt
• Navigate to the folder which contains the scripts you wish to test
• Type mavproxy.py --master=”com##”,57600
• Run your script by typing into the MAVProxy terminal
o api start script_name

ROS package not found after catkin_make

I created a ROS workspace following the Wiki page from ROS. I also created a package using catkin_create_pkg under the workspace I just created.
Then, following the steps in ROS Wiki to build the package using catkin_make, after the package is built, I insert the command rospack find packagename, and my package is not found anymore.
Can anyone help me on this?
Have you followed this basic tutorial? You have to create the package in your workspace and have set properly your Bash file (in your home directory).
To permanently set your system, add these lines
# ROS settings
source <your_workspace_path>/catkin/devel/setup.bash
at the end of your ~/.bashrc. Then, restart the terminal, and retry. Please, be sure to modify these lines with your actual information, where I've put <your_workspace_path> (depends on where you have installed ROS and its workspace on your PC).
If this does not solve the problem, try rospack profile before rospack find <your_package_name>.

Run .bat as a Windows Service

I'm here again with another case that is getting me out my mind.
So, this is happening, I'm trying to run an executable java class(.jar) as a Windows Service, and all my attempts failed so far. To make it a little easier, I turned my jar into a batch file, wich only executes the jar in background, here is the code:
start "" javaw -jar C:\LocalService.jar
The batch works fine. However I have tried to install this batch as a service by using the next line in cmd:
sc create "LocalService" binPath= "C:\LocalService.bat"
The Service installs correctly, but as soon as I try to start it, it pops up an error (The code error is 1053, says something about the service did not start correctly)
Also, I have try with a software called NSSM (non-sucking service manager) It installs fine too, but the service does not start either.
Do you guys know what am I missing?
By the way, I'm doing all this on Windows 7 Professional.
Thanks!
thanks for your comments
Both tools didnt work for me, sadly. However I was able to do it with a software called Java Service Wrapper. This is not a free software, so I needed to buy a license to get it to work.
The steps were simple:
1.-Create a folder with the name of the service, then inside add 4 folders: lib,bin,logs,conf
2.-On the lib folder you have to copy your jar and also the wrapper.jar and wrapper.dll (these last two are in the zip you download from the website)
3.-Copy 4 files to the bin folder: InstallApp-NT.bat.in, App.bat.in, UnintstallApp-NT.bat.in and wrapper.exe (this last one is the one that defines your license, if you can get a file wrapper.exe from somebody else who had paid a license it will work fine. These file also came in the zip from the website) Remove the .in from the batch files
4.-The most tricky step is this: You have to copy from the wrapper's folder called conf a file called wrapper.conf.in Remove the .in extension and edit it with a tex editor. The most important lines you have to edit are:
wrapper.java.command=C:\Program Files (x86)\Java\jre7\bin\java //Specify JRE Path. Will work with eviroment variable
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperJarApp //Choosing this class means your are using a .jar file to execute when the service starts
wrapper.java.classpath.1=C:\LocalService\lib\wrapper.jar //This one is constant.
wrapper.java.classpath.2=C:\LocalService\lib\LocalService.jar //This is the path to your executable jar
wrapper.java.library.path.1=C:\LocalService\lib //Path to your own lib folder (the you created at the begining)
wrapper.app.parameter.1=C:\LocalService\lib\LocalService.jar // again the path to your jar
Then just execute the InstallApp-NT.bat and start the service and your are done
It worked to me with absolute paths, however according to documentation it will work fine with relative path too.
This is how I solved my problem and I hope someone with the same issue will find this helpful
See you next time!
