Im doing the big update the 34gb update, and when its done updating, it gives me this error "INSTALLATION FAILED DISK ACCESS PROBLEM" is there a fix to this?

error reads (INSTALLATION FAILED: DISK ACCESS PROBLEM 1.31a)

Yes.

Could you point me to the right diretion for the fix?

Sure, when you provide more information. Operating system, Galaxy or manual install, path to installation etc. The more information you provide the better help you will receive. The reason I was curt is because you were.

Sure, store bought game installed using the 6 dvd's, OS is Windows10, after installing the game works and plays fine, but while gog updates it the 34 GB update that takes a long time, after it updates it gives that error at the end. then after a few seconds it starts the update all over.

I can manualy play the game by going to the bin>64>the click on the exe. But that update seems to always restart its self once it completed its 34GB download.

Do you have enough free space on C partition?

Yes i got 155GB left free

If I was you, I just delete the game and install from galaxy.

so uninstall the game via PC, and download the game from Galaxy? Will i lose my saves?

Before you go re-downloading again, do you have active antivirus? These kind of errors can be caused by antivirus preventing proper disk access. Disable any and all security programs (antivirus etc.) while you install.

Just move the save files in another location before uninstall.

I installed it with GOG Galexy, no problems so far, working good now.
