Hello,

I have been trying to download Thief 1 and Deus Ex for the past hours and each time, the download is corrupted.

The 3st times: direct download
4th time: downloader (latest stable version)

I tried once on the downloading computer (vista 32b) and it seemed to work. But once on win 7 64b, the integrity file checker fails at the end.

Is there a problem at GoG or is it me?

I honestly don't know, but I have no problem downloading and installing Deus Ex on Windows 7 x64 (didn't buy Thief yet).

The downloader should be checking and fixing corrupt segments as it downloads, so I doubt it would complete if it weren't correctly transported. I'd be guessing your hard drive or internal transport (router, network, etc.).

Try to a different device, then put it on a usb key and install from that. If that works, you have problems to fix, but not to do with GOGs.
