Its easy, go to my computer>right click the D drive (or whatever letter your dvd-rom is ) and open the 1946 disk. You are looking for a program named " A" ( see pic below). Double click it,it will say are you sure you want to uninstall 1946? Dont worry it wont so click yes. After it runs through that it will start to install and give you the option of where to install it. You can install it anywhere you want on your computer. That's the same way you can have multiple installs, you just have to rename the ubisoft folder first. Hope that helps.

Logan,
Thanks for the reply. Same result though, starts to do something then quits.

Logan,
Would you believe after 20 minutes of nothing, the programme loaded!

Me too, just reinastalling IL2. apparently im now cured of my MMO an Skyrim addiction so my normal levels of insanity may resume.
Just found out about facetrack noir yesterday, couldnt get it working so i blasted off into local town an picked up a cheap as chips new webcam. works like a dream in ROF. Now lets see what i can do with this old girl. Bored to death while i wait for 4.11 patch to d/l.
IF an (judging by how quickly i got ROF whipped into shape), I can get this running just as slick you wonderful mad men an ladies of the big blue yonder might just grab my attension again

May I interject here that if any of you born-again pilots are looking for a squad to join may I recommend Chuffy's Heroes? A fun-loving bunch of chaps from across the globe I have the pleasure to fly with:

Something I noticed when I delete a (IL2 copy-mod) folder, it does not matter if I called it IL2-DBW folder or other. If I delete it, all stock game-folders don't work anymore and I can't use the DVD ether. All mod-folders (Il2-exe) are still working.

strange.

If you are using a Mod Enabler like JSGME, you must switch your game back to stock before removing files or you will corrupt your install.

NOW it sounds like a secure ROM issue.
Get this man the NOCD.

Glad that worked for you guys! And yes Get that man NOCD!
