That looks like an extraction issue. Note that the folder listed is a temporary folder. My suggestion is this:
1.) If you can, redownload the mod. Hit "Save" instead of just "Open" (skip step 1 if you can find the file in a folder that isn't temporary with a crazy name, like C:\Users\xxx\Downloads)
2.) If I recall, it is a 7z file. Using 7zip, copy the mod outside, into the "Downloads" or "Desktop" or whatever, just not directly in Program Files. Copying directly into Program Files from a program that isn't just Windows Explorer can cause weird issues exactly like this.
3.) Make sure permissions are right in the folders you are copying to. Is your account Admin? Is the folder listed as Read-Only?
Try some of these and I will try to give more suggestions.
Side Note -- you may want to run Windows Disk Cleanup Program or CCleaner to clean out that folder in case something in the temp folder is causing weird issues.
