In my Visual Studio 2005 project properties I have "Additional Include Directories" configured as:
"C:\Program Files\gecko-sdk\idl";"C:\P
C:\Program Files\gecko-sdk\idl contains nsISupports.idl which I am including in my project file (along with other files that nsISupports itself includes).
After copying the project from one hard drive to another, this include is for some reason not working. I am guessing there is some configuration file that has an invalid reference or something, but in the project config the include directories are set correctly, so I'm not sure what else I need to check.
This is the error in BuildLog:
Creating Type Library...
Processing .\RCComponent.idl
RCComponent.idl
.\RCComponent.idl(1) : fatal error C1083: Cannot open include file: 'nsISupports.idl': No such file or directory
midl : command line error MIDL1003 : error returned by the C preprocessor (2)

I have indeed verified that the file is in the location specified in Visual Studio.
I was editing only the "Active (Release)" configuration so I tried setting the include directories in "All Configurations" as well but still getting same error.
I also tried changing to progra~1 instead of program files, but still no luck.
Also I deleted the entries and used the browser in Visual Studio to add the two directories again, which hasn't worked either.

Not sure if this will solve your problem, but I notice you have spaces in the paths, which may be partially due to your error. You can try it with "c:\progra~1\gecko-sdk\idl
Alternatively, to be absolutely sure you typed everything correctly, copy the directory and paste it in an explorer window and check the existence of nsISupports.idl (but you probably already tried that).
Third idea to check: have you changed the active configuration? When you add the include directories, did you add it after first selecting "All Configurations" in the property pages of your project?
