I'm using VS 2019 (Image 0)

Since the last update I'm getting this error trying to update projects: (image 1)

Failed to execute command.

I have tried to remove and reinstall from Telerik control panel, it didn't work.

I also tried removing and reinstalling the extension within visual studio. it didn't work. 


I have found that the path c:\users\jonovoa\appdata\local\microsoft\visualstudio\16.0_8573c414\extensions\akzfqu3o.rq0 (image 2)

does not contain the folder mentioned in the error description: 



I just noted that I have another path with all the files: (image 3)




Visual studio throws a couple of warnings due to UNRESPONSIVE EXTENSIONS, with the following offenders:

"Progress Telerik  UI for Winforms Extension version 2021.2.505.1" (image 4)

"Progess Telerik WInforms Converter version 2021.2.505.1" (image 5)


My installed version is: R2 2021 (2021.2.511.0) (image 6)


Please help me to solve this.

Hello Jorge,

Thank you very much for the detailed information. This error is a known issue that is fixed but not released yet. We will release the fix in a few weeks.

The problem is related to shared resources across multiple Telerik extensions. In your case most likely they are Progress Telerik UI for WinForms Extension and Progress Telerik WinForms Converter. To workaround the problem you can disable or remove the Telerik WinForms Converter extension from Extensions -> Manage Extensions -> Installed.

If the proposed workaround does not resolve the problem, please, let me know what is the content of the extension.vsixmanifest file in c:\users\jonovoa\appdata\local\microsoft\visualstudio\16.0_8573c414\extensions\akzfqu3o.rq0\ to determine which extension causes that error.

Thank you very much for your patience and cooperation.
