check if a file is running from c:\windows\system32

i am kind of stuck with having to try and figure out if a process is running from c:\windows\system32....
ive got something like ..

if(pe32.szExeFile && Path)

Path is used with GetSystemDirectory(Path , 100);
any idea why this wouldent work?

so you have a name and you want to know if a process is running??
