Just downloaded the IL-2 Sturmovik: 1946 and tried twice to install. On both times the installer processes for over an hour and finally informs me that I don't have enough memory (Didn't write down the exact error message, sorry.) I'm running a AMD Phenom 8450 (2.1GHz) with 3GB RAM so either I'm having a brainfart or I should be happily over the minimum requirements. Any help would be greatly appreciated.

I don't know, it's best to contact support for this.

If you were using the GOG downloader, try disabling it and download the game directly from the game shelf (or the other way round).

It really would be useful to get the exact error message it's throwing. Better yet, a screenshot of it...
