Hello, Magnus. I read the -bugs thread that resulted in this code and 
choose not to comment since I thought that perhaps my understanding of 
the implications of using SHFolder.dll v. Shell32.dll was in error.

However, installer code that I had authored before that works on both 
98, XP, and NT does:

module = LoadLibrary("SHFolder.dll");
if (module != NULL) { getfolderv1 = GetProcAddress(module, "SHGetFolderPathA"); ...  invoke function, deal with ANSI
path... FreeLibrary(module);
 
} else { module = LoadLibrary("shell32.dll"); if (module != NULL) {  getfolderv2 = GetProcAddress(module,
"SHGetSpecialFolderLocation"); ...   invoke function, deal with UNICODE path  ...  FreeLibrary(module); } else {
throwan exception here... }
 
}

I think the way to guarantee success is to ship the redistributable dll, 
shfolder.dll with the application, which would eliminate the need to try 
and fall back to shell32.dll. shfolder.dll is redistributable:

This article explains what needs to be done to write an installer for 
older platforms:

Note:

"Important: SHGetFolderPath is new to the Windows 2000 API. If you call 
SHGetFolderPath from an application that can be installed on a previous 
version of Windows, then you will need to redistribute the file 
SHFolder.dll with your application."

as does this one:

My code expects to find an shfolder.dll on < Windows 2000 systems and a 
shell32.dll on >= Windows 2000 systems. As I said, I *believe* you can 
guarantee success by just shipping shfolder.dll with the application.

Hope that helps,
