Could not load file or assembly 'Microsoft.Windows.Design.Extensibility, Version=, Culture=neutral


Hello @Manju_Reddy_Kanughula
May we know what you are trying to do? where you encountered with this error??


While installing the REFramework I am getting this.

Hi @Manju_Reddy_Kanughula

Have a look on the thread

Try this solution:

  1. Download the Microsoft.Windows.Design.Extensibility.dll from the attached file (60.7 KB)

  2. Extract the zip file and copy the file Microsoft.Windows.Design.Extensibility.dll to the folder C:\Program Files\UiPath\Studio\net461 or C:\Program Files (x86)\UiPath\Studio\net461

  3. Remove the dependency UiPath.Testing.Activities 1.4.4 from the RE Framework project in case you have it.

  4. Rename the packages folder from the %userprofile%.nuget\packages to packages_old.

  5. Retry to run a job in the impacted robot machine.

If the above solution didn’t help, upgrade the Studio to a higher version (22.4.6 or 22.10.3).
