Recently tried to download this thing via the torrent because I really love this game, but after I used winrar and tried to run the installer i kept getting the isdone.dll / unarc.dll error (code -1) about 40% through. i tried a lot of the fixes online like turning off windows defender and, running recheck, clearning temp and much more but nothing works. does anyone else still have similar issues? also interestingly enough the purple screen on the installer will shrink midway through and red error text appears underneath not sure if that helps.

im running this on a laptop with 16GB RAM and intel core ultra 7 155H if that helps

try the low hardware button on the installer.

***CAN CONFIM THIS WORKS***

I had this problem and the 100% answer is get latest Microsoft.Visual.C.Redistributable.Runtimes.Aio and this will solve you problem.
