RA mod and win7

[Tubbmeister]

Hello - I'm very new to this, but enjoy the game and cannot get the RA mod working. I've tried both 1.31 and 1.32. I've installed DW into C:\DW, patched to 1.4, tried to use administrator rights to install the mod, but during the installation see many "file not found" errors. When running the game, the splash screen appears, then the RA intro video, but when I then try to move into the core game, it crashes.
Please just confirm that the correct installation method is to copy the mod files directly into the DW files, then run the patch from, in my case, c:\dw?
Any help much appreciated......
