How can I tell the difference between outlook express 6.0, 5.5, and 5.0 by looking at a file or registry? I guess what I'm needing is the version number of 5.5 and 5.0

I've searched for "outlook express" and "version" on the board but didn't find what I needed. I've queried the file at C:\Program Files\Outlook Express\msinm.exe, I've also looked at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Outlook Express\Version Info, the "Current" value. They both say 6.0.2800.1123. Is it safe to say that 5.5 versions will say 5.5.xxxx.xxxx and 5.0 will say 5.0.xxxx.xxx? If this is so I can use an
Code:

If Instr($OutlookVersion,"6.0")<>0

Our servers are all updated to 6.0, but I'm writing a script to query the verion on the client machine and have never queried for outlook express..

I only need the version info, I can write the script easily...

Thanks in advance...
