yeah, could totally be virtual memory if it's a huge repack. had that happen once. try manually upping your paging file size in windows settings. also, sometimes it's just your antivirus blocking something, so maybe disable it temporarily during install. and run the installer as admin too, always helps with those repacks. good luck!
 
The isdone.dll error returned an error code: -1 usually appears while installing large games or software when the installer cannot properly extract files. It is commonly caused by corrupted installation files, insufficient RAM, low disk space, or antivirus interference.

To fix it, re-download the installation files, disable antivirus temporarily, ensure you have enough disk space, run the installer as administrator, and check your system RAM for errors.
 
if it's a specific repack from one source, sometimes the archive itself is corrupted or partial. before reinstalling the whole thing try opening the setup files with 7zip and let it test the archives - if any are bad you'll see CRC errors and that's your culprit. then a redownload (preferably from a different mirror) usually fixes it. otherwise the paging file fix mentioned above is solid.
