When the automated test project is created, this error occurs

Could not load file or assembly ‘Microsoft.Windows.Design.Extensibility, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The system cannot find the file specified.

Hi @Guanghao_Sun,

Welcome to the community. You have tagged your question incorrectly. It should be tagged as help and not feedback. Feedback is dedicated for proposing features.

This seems to be affecting many studio installs and is linked to a bug in UiPath studio. The fix is not released yet.

You can however read this article to try the two workarounds posted. It might fix your errors. If not in the current project, as the workaround two suggest, for future projects at least.

Hi @Guanghao_Sun

As stated above, it is a bug and our team is working on a fix. The workarounds linked above should help you though, but please let us know if you have any issues.


@Guangho: An other quick workarround is to go to lower package versions in package manager of Studio. Not the best - I know.
