Does anyone else have difficulty with this problem? SL is already installed on each of my browsers but, sometimes (not all the time), the browser shows the SL logo asking to install it. Is there a reason this happens even though the website works perfectly at times? When I re-load the page the logo usually goes away and solves the issue.
Thanks!
Often this is a version issue, in that if the silverlight app was compiled against a newer version than what is on your machine, you will get that SL logo. However that doesn't explain why a reload of the page solves your problem.
HKEY_CLASSES_ROOT\AgControl.AgControl does not have READ access fix
Run regedit (start->run->regedit)
Navigate to HKEY_CLASSES_ROOT\AgControl.AgControl (if you get a message that says "AgControl.AgControl cannot be opened. An error is preventing this key from being opened. Details: Access is denied." proceed to the "Taking ownership of the key" section)
Right click and choose "Permissions"
Click "Add"
Either add your windows username or your network username in the the "Enter the object names to select" and click "Check Names". Your name should take the proper format. If it does not try clicking "Advanced" and searching for your username. My windows username was the one I used.
Click OK
Select your new username in the top pane and in the lower pane (Permissions for ) check the Allow box next to Read.
Click OK
Check Silverlight installation in IE by going to http://www.silverlight.net/
Taking ownership of the key (If you're getting access denied errors while trying to set permissions)
You can download the following tool from microsoft to open an
instance of regedit as system:
http://technet.microsoft.com/en-us/sysinternals/bb897553
The following command line will open a "system" regedit:
psexec -s -i regedit
(Note: You have to execute this command line from an "administrator" command
prompt [right-click command prompt and click run as administrator])
Return to step 3 above

Hi I'm trying to implement a Group Policy in our domain that forces Google Chrome to be added to client startup applications. I've added a GPO and added the key:
Computer Configuration > Administrative Templates > System > Logon > Run These Programs at User Logon
In the "Items to run at logon" I've added the path to chrome.exe (with quotes) like so:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
I've then linked to the Object in our Domain's User and Computer OUs.
I've also pushed the update out to clients and confirmed they have updated GP.
However Chrome does not start when users boot into their laptops.
I'm hoping someone can shine a light on what I've done wrong/what I've forgotten to do - any help much appreciated!
Summarize the comment link as a reply to close this issue.
Per duenni1's comment it looks like the most successful way people are reporting is to use the startup folder instead of the logon group policy. "In my opinion the correct solution: use GPP to manage shortcuts in startup menu folder. Simply create a startup shortcuts."
Could throw it in this directory:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
This will launch the program when they login, we do this to force users into our IM client
https://community.spiceworks.com/topic/1369848-run-these-programs-at-user-logon
If you really want this method to work, I'd start troubleshooting here:
1) is there already a GPO in place that will perform Run These Programs at user logon? That may be the winning GPO
GPO Run these programs at user logon not taking effect
2) According to the official docs, no error is a path issue ( I think your usage of quotes is correct but out of curiosity I'd be curious if removing the quotes has a change).
NOTE: If the program does not run, make sure the path is correct. The program does not run (and no error message is displayed) if the path is not found.
I am distributing Firefox ESR in an enterprise environment, including a homemade WebExtension in the distribution\extension directory as explained in https://support.mozilla.org/en-US/kb/deploying-firefox-with-extensions
This instance of Firefox is installed to be used for a particular set of applications and is not intended to be used as the user's main browser. It is launched through a cmd script with a specific profile, for instance :
Firefox\browser\firefox.exe -profile myParticularProfile
Starting Firefox this way creates the profile if not already present, and the profile will not be visible in the profile manager.
Everything is fine after initial installation : every new profile of every user will get the extension copied to the extensions directory of its profile, and the extension is activated.
However, I need to be able to update the extension without reinstalling Firefox. The problem is, the updated extension does not get copied to existing profiles.
The documentation says that the extensions will be updated when Firefox is updated, but I need to be able to update the extension without updating/reinstalling Firefox.
Clearing the "extensions" folder in the profile does not solve the problem (the extension does not come back with the update version as I hoped)
I also tried clearing various cache directories without success
I hope I will not need to write a command script to update the extensions myself since I am not certain I will be able to easily locate and modify every user's profiles.
Maybe suggesting to firefox that it has been updated (even if it is not true) would do the trick, but I do not know if this is possible.
Any ideas ?
I have downloaded Oracle Developer Days Database 12c virtualbox image. I can boot it and access the desktop. When I try to log in to Enterprise Manager (EM) Express using the URL http://127.0.0.1:8888/em I am asked to install Adobe Flash. I install it and get to the login screen.
If I try to login as SYSTEM I get the following error:
But when I try to log in as user SYS I get a strange error: Security token does not match. You must login again..
To me it looks like the credentials for SYS are OK, but there is something wrong with the user in the database. Is this correct and if so how can I fix it? Or is EM Express just not setup on the image?
This document from Oracles Metalink solves it. The solution contains 3 steps:
Make sure that XDB_WALLET is recreated successfully.
Make sure XDB is installed successfully and the appropriate roles, EM_EXPRESS_BASIC/ALL is applied.
Use IE 11.0.9600.16476 with compatibility view.
Mark Stewart's answer covers step 2.
The first two steps are not strictly necessary. It looks like they have already been applied to the image in my case. All I had to do was use a different browser. Opera, Chrome, and IE all worked, but Firefox didn't.
The fact that Oracle installs a browser that doesn't work with EM Express and that Adobe Flash is not installed when it's required is very strange.
Set up a personal user ID, grant DBA to it, and try granting EM_EXPRESS_ALL role to your user ID.
After making sure that a desired account has EM_EXPRESS_ALL granted I just accessed Enterprise Manager using New Private Window in Firefox.
In Microsoft Edge, no problem accessing Oracle 12c EM
In Microsoft IE 11, no problem accessing Oracle 12c EM
In Firefox : Security Token does not match
Found a solution for Firefox on Is there a way to make Firefox ignore invalid ssl-certificates?
Go to Tools > Options > Advanced "Tab"(?) > Encryption Tab
Click the "Validation" button, and uncheck the checkbox for checking validity
Be advised though that this is pretty unsecure as it leaves you wide open to accept any invalid certificate. I'd only do this if using the browser on an Intranet where the validity of the cert isn't a concern to you, or you aren't concerned in general.
I faced this because of the cookie data stored by Adobe Flash. Browsing on Private mode or Incognito did not help. Here are the steps to remove the stored data and start using EM on Chrome:
Go to Settings>Advanced>Content Settings>Cookies
Coose See all cookies and site data
In the cookies search box, key in the hostname used to access EM. I run EM on my localhost and hence filtered by localhost:
You can see Flash data being listed
Click on the item to expand and delete the item related to EM:
The same error still exists in 2019 on EM with Chrome Version 76.0.3809.87. My solution is to add EM URL to the "Allow" section in the Cookies section.
Use internet explorer to login to EM .
The other browser are not compatible with enterprise manager
I have added my own procedure to run as soon as user logs, using
SET OPTION PUBLIC.post_login_procedure = 'xxx.Myprocedure';
I need to set custom message on pop up this provides when user logs in. The pop up is working, when I manually login in from Sybase central.
however, when I run dbisql -c "DSN=myDSN" from command prompt Interactive sql opens and I get the popup that stays on forever!
I cannot post images yet but I can send u one, it says "Connecting to database.."
I get this pop up only when I have set the popup to appear through post_login_procedure ,
If i remove that then I can connect to interactive sql without any problem.
Please help,
Thanks
I maintain a large WPF application which I inherited from another developer. I use ClickOnce to publish it. Suddenly, today I got an error message:
Error 2 Cannot publish because a project failed to build. 1 1
Error 3 An error occurred while signing: Failed to sign bin\Debug\app.publish\setup.exe. SignTool Error: No certificates were found that met all the given criteria.
I do have a file called SomeName.snk, which is referred in project settings, Signing tab. I have no idea what happened today that caused the problem.
I use VS 2012.
Go to main project properties > Signing > If the expiration date is over > click on Create Test Certificate, password is not mandatory, and you're done.
I'd check whether the certificate expired. Most (all?) certs have an expiration date.
I got this problem installing visual c++ on top of a VS2017 .net install. I solved it by unchecking Properties -> Security -> Enable ClickOnce security settings.
It then created an app.manifest file. After that the error went away. Interestingly enough, I checked it again to see what would happen and the problem did not come back.
Did you check for the certificate?
View or manage your certificates
You can use the MMC Snap In or Internet Explorer.
Go to main project properties > Signing > Select from Store...
Click certificate properties
And install certificate
Go to Main project (Startup Project) and right click > properties
Then go to Signing
Then unchecked "Sign the ClickOnce manifests"
It's work for me.
This happens mostly if your certificate for that particular project has expired or has some issues.
Right Click Project -> Properties -> Signing Tab -> More Details button -> Shows your certificate details. Check if your certificate has expired
Ways to Fix
1. Un-check the "Sign the ClickOnce manifests" and try
2. Extend the Certificate by creating a Test Certificate (If your certificate is expired)
Hit "Create Test Certificate..." button
Enter your credentials (Not mandatory)
Save
3. Re-validate your existing certificate (If your certificate is not expired)
Hit "Select from file" button and use your existing key file (eg. .pfx)
OR
Hit "Select from Store" button and select from the available options
Tip: If you still face issues building the project. Just restart your
Visual Studio.
Hope that helps.
I had this same issue and I was able to solve it by removing or changing the timestamp server URL. After removing that, the project was able to build successfully.
I just ran into the problem today. In my particular case, it was caused by this Microsoft Windows Update.
I uninstalled that update and publish began working as it always had. This is only a temporary work around and means you should probably regenerate your keys/certificates.
In my case, the cert was not expired and none of the other solutions worked (restarting VS, using a temp test cert, restarting computer, etc.)
The issue was resolved by deleting my output directory and rebuilding.
Simple Clean sorted it for me.
Build - Clean Solution
In my situation I had many projects in the solution, so I browsed to the non-startup project and:
Go to main project properties > Signing > uncheck the Sign the ClickOnce option
Using Visual Studio 2019
