Error installing Tweak changes on BGEE

[Highborne]

I have just reinstalled BGEE after new updates on my new computer, went through the how to install mods thread (made backup of chitin, and linked folder through command).

 

I downloaded BG Tweak Pack and installed into my 00766 folder.

 

Running the installer for it and applying changes constantly gives me an error (it didn't before on my old comp). Says:

 

ERROR: COPY ~sw1h01.itm~ ~override/cdt00060.g3~ FAILED: cannot open target

Stopping installation because of error.
