Launcher Error - The Witcher 3

[Dan364]

I installed a few new mods and the Script Merger tool on The Witcher 3 and now when I launch it I get this error.

Unfortunately, in order to use the Merge Tool, you can't use Symlinks or Hardlinks, because the Merge Tool doesn't know how to use those.
What happens is, the Merge Tool looks like it's doing it's job, and reports that the mods have been merged, but it actually doesn't merge them, because of the symlinks/hardlinks.

 

What you have to do if you want to merge the mods successfully is to manually copy them into the appropriate Witcher Folders and run the Merge Tool.

I ran into this same exact problem myself just a few weeks ago.
