Place the files in the download folder. Do NOT unpack the file.
Files are corrupted when hashing
Check that your drive isn't full
Delete the corrupted files, and restart Wabbajack.
If the files keep getting corrupted it's possible an antivirus is interfering.
Try adding your Wabbajack folder (where the executable is located) and your selected modlist installation location to exclusions in your antivirus of choice.
If you're using a 3rd party antivirus (such as AVG, Avast, BitDefender, Webroot, Kaspersky, Norton, McAfee etc.) it's likely that adding the folders to exclusions will not be enough and you may need to disable or uninstall your 3rd party AV as they can incorrectly mark files like usvfsproxyx86.exe (required for MO2) as a virus.
We recommend doing so anyway as Windows Defender is likely much better at stopping threats, according to data from av-test.org: https://www.av-test.org/en/antivirus/home-windows/.
