Sorry for any inconvenience this has caused, but could you please find and remove any WeMod-related files from your PC? Also, delete WeMod from the AppData directory and Squirrel from the temp folder. After that, restart your computer and attempt to reinstall.
If the above doesn’t work and you’re still having trouble installing the app, I recommend you visit the thread below, as it contains recommendations from our experienced mod that can definitely help with such installation concerns.
