I have figured out how to make sure that is only install the once and not everytime the user logs on, this is done by check a key where the version number changes after the install the only promplem i have got is how to check if the key exists as the key i need to get the value from has got slashes in it. Here is the line \HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\DLLUSAGE\VP6\ then under there there is a value name under name which is C:\PROGRAM FILES\NORTON ANTIVIRUS\CLISCAN.DLL and then the value data is 7.51.850 is someone able to tell me how i can check to see if the value data is correct. I can't see how to put the information after VP6 in

Thanks
