Move the installer to the C Drive

Inspect the logs

The Wabbajack installer keeps a record of everything in a log file inside the logs/ folder. This is the usual way of investigating Wabbajack failures, before or after the installation. Go through the log file to find out what went wrong and try applying the fixes recommended before trying again. 

Check the modlist

Another possible reason you’re getting this error could be that the modlist you’re trying to install is corrupted or outdated. Check the opt-out list hosted on GitHub here to see if the modlist you’re trying to install is still supported and if it isn’t, try switching to a compatible version before you run the installation again.
