Yeah, I've gone through the usual solutions (W7/64) here.

Got the icon in my quick start bar, but the installation window never appears however long I waited. I contacted support yesterday, but - well, weekend. :(

* used the gog downloader (for the first time yesterday. will not repeat)
* ran as admin
* deactivated virus scanner
* deactivated UAC
* downloaded the exe once again

Corrupt RAM is BS, and the file integrity is never checked, so I think it can't be corrupt files as well.

What now??

I have the same problem. When i try to run installer it says that the source file is corrupted (Runtime Error (at 138:424)) and that I should run integrity check, but that's impossible. Is it possible that there is something wrong with files on the gog server?

Same problem here.

me too. can some one please help!

Sounds weird, my copy installed just fine (Win 7 64 bit. Installed to non-system partition). Have you tried re-downloading the whole thing?

I have experienced some downloading issues with other games recently, but usually closing and restarting GOG.com Downloader has solved those issues and I never had any problems with Chains of Satinav.

i redownloaded without the gog installer, and it worked.

i hav edone a little sience and found out that package 3 was always corruptet when downloaded with the downlaoder and worked fine downloaded without installer.

i reportet it the same moment i found out and now everything seems to work fine.

i think i deserve some reward ;)

Same here, the downloader doesnt even start and crashes.

I think its abadonware.

Downloading Witcher BoardGame through direct download and it takes 4-5 hrs to download.
