So on my brand new Windows 10 PC, I have tried to install about 11 installers.
Only two of these has worked, and those were WinRAR and No Man's Sky.
The installers I tried were for games, namely Alien Isolation and the GOG installer for No Man's Sky, and
also Batman: Arkham Asylum.
All failed installers always returned an error of "ISdone.dll (title) unarc. dll failed to decompress" or "failed CRC check".
I've tried some of them on a separate computer, with no luck.
Redownloads and Force ReChecks done, and with the same result.
Is there anything I can do?
