I have 16gb ram and over 10tb space and never had any troubles with other games just this one and the Quantum break and apart Xcom 2 which sorted as Pakrat sorted the ultraArc had trouble with, all the rest works fine soon as do them so no worries on them at all as even did hitman 2 full conversion no probles either as that was a big install.

@Steveboss

Read the entire first page as to where the game is expected to be other then on Drive C ( its a special location for C ) . but other then that how are you compressing the game
Ultraarc or Diskspan ?

Did this again and I got to ge this going and it went all the way to end of Dat.bin.01 with about 20 seconds left and then get this error "WARNING: FreeArc returns an error in archive Data1.bin.001 Do you want to try again? [Y/N]:" and there is only Diskspan no UltraArc in folder which thought strange as UltraArc is best to use in my opinion. Game plays well and took about hour install it and nothing wrong in Appfiles either as last time played got error message but not now as windows is fully updated as states need to be. Will install C: drive as I have it installed on F: drive where all games are put and see if that makes a difference with Diskspan as that all got to use in folder.

@Stveboss, then grab ultraarc files from other conversions youve done & add them to this one.
