Help:Unarc.dll error code: -1 Fitgirl repack
Hello, I am trying to install Rocket League (v1.35 Anniversary Update + 16 DLCs + Offline Unlocker) [FitGirl Repack] 2.8 GB.
I installed it successfully at first, but then uninstalled it.
Now, I am trying to install it again but the setup gives following error at 90.9% :
An error occurred when unpacking!
Unarc.dll returned an error code: -1
ERROR: archive data corrupted(decompression failed)
This is self explanatory but when I tested the bins with QuickSFV with the md5 provided, all bins are OK! So,the problem is definitely not the bins. I followed steps for troubleshooting but the error still persists.
What should I do now?
Edit:- Found the solution guys. It was incomplete download. I checked the hash on my torrent, some parts were not downloaded. Hence,the archive data corrupted error.
