I have a .NetFramework4.61 WebAPI. I am trying install IdentityServer3.AccessTokenValidation & System.IdentityModel.Tokens.Jwt using Nuget but it is giving me the below error. I also try to install using package manager console that too also failed
>Install-Package IdentityServer3.AccessTokenValidation -Version 2.14.0
>Install-Package System.IdentityModel.Tokens.Jwt -Version 6.11.0
How to resolve this issue?

One or more errors occurred.

Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 172.16.20.241:11688
This seems to be lack of nuget source issue and you need to add the nuget source for nuget.org and then try to install the package
Add a nuget source point to https://api.nuget.org/v3/index.json on visual studio
Install the package again. You can select the package source on package management console on visual studio or specify it in the command as bellow:
PS> Install-Package IdentityServer3.AccessTokenValidation -Version 2.14.0 -Source nuget.org

How to configure PDFNet for .NET application to publish to Citrix server? (AnyCPU)

So I have been trying to config the project to make it work on our server via Citrix.
I used this line of code to set the path:
private static pdftron.PDFNetLoader loader = pdftron.PDFNetLoader.Instance().Path(String.Format(#"{0}\{1}",
System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetAssembly(typeof(IndexUIZoom)).Location), #"PDFNet"));
I got this error every time (bin is where the .exe file is):
INFO Program [(null)] - Path: [bin]\PDFNet -
ERROR Program [(null)] - System.IO.FileNotFoundException: Could not load file or assembly 'PDFNet.dll' or one of its dependencies.
The specified module could not be found. File name: 'PDFNet.dll'
Everything works fine on local machine. I got the error above whenever I run from Citrix, or log into the server machine and run from there.
Most likely your server is missing the MS VC++ Runtime dependencies. Developer machines usually have them installed as part of a Visual Studio installation, but servers often do not. You can download MS VC++ installers from MSDN.
To find the exact one you need to download please see section 3.2.1 of the Getting Started Guide for PDFNet .Net below. Note you need to also match the runtime 32 or 64 bitness of your process, for both PDFNet.dll and the MS VC++ runtime.

Javascript error on new install of 7.0.1.0.2

I've had a good look around and can't see anyone else with the same issue.
I've downloaded the latest install for DNN (via this page https://dotnetnuke.codeplex.com/relea...) and tried to run it as a new install (via visual studio development web server) but the site crashes on the second page of the wizard, I get a javascript error "Invalid character" in the jquery library and nothing happens are that.
Using the VS javascript debugger I can see in the call stack that the error seems to stem from some javascript used to update the progress bar found on the installation page, the line in question is...
var result = jQuery.parseJSON(status);
If I let the code run from here I get a further error of "Unable to get property 'progress' of undefined or null reference" in the same block of javascript code a few lines down...
if (result.progress < $("#progressbar").progressbar('value')) return;
Details of my installation;
Running on Windows 7 64 bit (have also tried a Windows 7 32 bit but get same error).
Using VS 2010
Installing to new (blank) database on MS SQL server 2008
Using a SQL user for authentication
Have tried the suggestion of "unblocking" the zip file before downloading
Given the NETWORKSERVICE user full control over the DNN website folder
I've tried the installation with IE 10 & the latest version of Chrome (30.0.1)
In addition to trying to run the installation using the wizard I also found that you can disable the wizard via this web.config setting;
Running with this I am able to successfully install DNN but when redirecting from the basic wizard page to the DNN site I get an object not set to an instance of an object error on this line...
if (PortalSettings.ActiveTab.PageHeadText != Null.NullString && !Globals.IsAdminControl())
... of the default.aspx code behind
I had a play with DNN 6 last year and didn't have any issues installing so to confirm that was still the case I downloaded the last release of DNN 6 (version 6.0.2.09 from here https://dotnetnuke.codeplex.com/relea...) and was again able to install that version without any problems at all using the same SQL server and running through VS 2010.
Any help would be appreciated.
Thanks,
I was having the same problem and switching the pipeline mode for the application pool to "Integrated" fixed the issue on PortalSettings comming on null on this line:
if (PortalSettings.ActiveTab.PageHeadText != Null.NullString && !Globals.IsAdminControl())
