Hi All,

I use for development Microsoft Visual Studio 2010 Professional under Windows 7 Enterprise.
Recently I installed the released Telerik RadControls for WinForms Q3 2010. When I started VS for the first time after this installation, the Extension Manager of MSVS2010 notified me that an upgrade from the version 2010.2.505.0 to the version 2010.3.1109.0 of Telerik WinForms VSExtensions is available. I gladly have tried to update this extension, but after successful download an error message suddenly pops up:
"Extension Telerik.WinControls.VSPackage must be uninstalled through the Windows Add/Remove Programs dialog."
The more unfortunate outcome is that the Upgrade Wizard disappears from the Telerik menu in VS.

Can you please explain how to update the VS extension?

Thank you in advance.

-- Best regards

thanks, this worked....

This solution does not resolve my issue, I do not have the %localappdata%\Microsoft\VisualStudio\10.0\Extensions nor the  [VisualStudioInstallDir]\Common7\IDE\Extensions\Telerik folders.

I am running Win 7 Enterprise, 64bit.

This is the error from the VSISInstaller....log

I have both try updating the VSextension through the Extension Manager in VS2010 as well as double-clicking on Telerik.WinControls.VSPackage.vsix.  Both fail with the error above.

Any other ideas?  

Hi Bill,

Can you check the Programs and Features Control Panel snap-in for older RadControls for WinForms versions?
Can you uninstall it if found?

Or, alternatively, we can use a GoToMeeting session so that I can help having this fixed quickly. Just start a private support thread and let me know a convenient time so that I can arrange the session (we are based in EET, GMT + 2).

Kind regards,

Hi Erjan,

I resolved it by removing the old WinForms control (2010 Q1) then installing the latest WinForms control.  Then reinstall the old (2010 Q1) WinForm controls.

However when I use the UpdateWizard to convert my solution to 2011 Q3 controls, it fails to convert radCombobox or radTabStrip (as well other decapitated controls) to the new controls.  Nor do I see the "Conversion Wizard" as described in http://blogs.telerik.com/blogs/posts/10-08-10/sp1-of-radcontrols-for-winforms-q2-2010-released-featuring-conversion-wizards.aspx 

Any ideas?

Hi Billv,

Being obsolete for more than an year, we removed the obsolete controls implementations in Q3 2011. However, as you can see from the screenshots in the blog post, the Convertion Wizards are available from the SmartTags of the obsolete controls. Therefore, I would recommend uninstalling the currently installed version, downloading Q2 2011 SP1 installer and applying it on your machine. Q2 2011 SP1 (v2011.2.11.831) is the last version that still contains the obsolete types, so the Convertion Wizards are available there. You can download Q2 2011 SP1 from Your Account >> Download and Manage your products >> Telerik Premium Collection for .NET >> Download Installer and Other Resources >> RadControls for WinForms >> Older Versions >> 2011.2.11.831.

After you upgrade to the new controls, you can then update to Q3 2011.

More information about the wizards can be found here:

I hope this helps.

Had the same issue with WebUI VSExtensions and applied the same fix from Telerik with success.

Hi,

We are converting a large project to use telerik controls, so we can bring our application up to date with theming etc.

The app has >200 text boxes within it - all standard VS2010 Standard.Windows.Forms.Textbox - will installing the Q1-2011 Telerik controls offer the tag sensitive upgrade option to a telerik textbox or does it just do old telerik controls?

We currently have Q2-2012 controls.

Thanks

 Terry

Hello Terry,

Thank you for contacting us.

If I understand you correct you are asking for automated upgrade path that will replace all standard text boxes with Telerik text boxes. To my regret we don't support such option. When converting a standard project to a Telerik project the VS extension only adds references to the Telerik assemblies. It doesn't change any code that you have.

If you have any further questions, don't hesitate to contact us again.

Kind regards,
