UiPath Could not load file or assembly 'UiPath.Interop

Hi if anyone is familiar with UiPath Studio i have this error:

Open Browser: Could not load file or assembly ‘UiPath.Interop, Version=, Culture= neutral, PublicKeyToken=461894da7f0ba157’ or one of its dependencies. The system cannot find the file specified.

I have tried reinstalling excel.activities but it still does not work. I am currently using 2 version of UiPath. On the Studio 2019.10.4 Enterprise version it gives this error but when i am using Studio Pro 2020.10.2 Community License there is no error. I want to be able to stay with the Enterprise version and not update it if possible. Anyway to fix the dependencies for it?

Hey @ongqiyu, Welcome to the UiPath community :slight_smile:

Thanks for posting the issue.

Please find this thread if it provides any resolve for you.


Hi @Nithinkrishna nope i have tested this and the only solution i found that helps was to update UiPath Studio which i initially din’t want to. It seems to me that the version compatibility of UiPath and it’s packages is lacking and would help a lot if we can save the work done with older dependency to enable compatibility with more workstations.
