Need permission for Bat file to remove Directories in Program Files

I have created a bat file that removes Directories, and subdirectories, however... it will not remove directories, and subdirectories from Program Files. How to I give this bat file rights to remove these directories from Program Files. No laughing please... here is the simple bat file I have created. What do I need to do?

How about using DELTREE /Y
Or is that not valid anymore? :o

Since "Program Files" contains a white space, you need to put the whole string (starting from c:) under quotes ("c:\program files\.....")
Actually you don't need to quote the whole string.  This should work:

echo y | rmdir /s /q c:\"Program Files"\Novadigm\lib\SYSTEM\PLSNOVTST102
