I've downloaded this game four times and have gotten a corrupt file error each and every time. I've tried everything, including turning off my Anti Virus and nothing seems to work. I am really hoping that someone here has a solution to this problem. BTW I've emailed support but I haven't recieved anything yet.

I second, I've downloaded the files twice, to no avail... Corrupt files both times. Please correct, I'll finish Commandos soon and want to pursue in Commandos 2! ;)
(I'll send beer to Poland if it makes things go faster!) :p

If you guys are using the downloader, try downloading it with your browser. If you're using your browser, try the gog downloader or a different browser.
I don't have this pack, but the game card indicates a file size over 2 GB. That means that if you're downloading it with your browser, there will be more than one file that you have to download before being able to install.

I've tried both the downloader and browser... it didn't change a thing.

How many files are there with the browser ? 2 ?

There are three files.

And you downloaded all 3, with your browser, to the same folder on your PC before running the setup ?

Yes and I still get a corrupt file error.

Ah, ok then. There's always a chance something went wrong with the file on the server, and if that's the case support needs to fix that.
You already made sure that you're AV/Firewall aren't getting in the way, right ?
I guess you could always try a different browser just to see if it makes any difference, or if you have the chance, you could try to download the files from another PC on a different location. Obviously if the file became corrupt on the server none of this will make a difference, and in that case we're back to waiting for support...

I tried downloading the files with the latest version of Firefox with my browser (and not the downloader), if it can help support fix the problem.

You should send support a ticket about this issue, if you haven't done so already

Oh, will do, didn't thought they had that here. Thanks! :)

They're surely busy as hell. No reply in two days... Thankfully I got other games to play during the long week-end, else I'd go crazy! ;)

Hello. I know I'm reviving this topic after 3 years, but I was having the same problem and checked the forum. Then something lit up in my mind and I tried to rename the files. If the .exe and .bin files have the same name (and also in the same directory), the "Corrupted File" problem fades away. You just need to add "-1" and "-2" to the .bin files. For example:

Commandos 2 & 3 - Setup.exe
Commandos 2 & 3 - Setup-1.bin
Commandos 2 & 3 - Setup-2.bin

Voila! I hope that helps everyone who's having the same problem.
