I've tried compatibility mode and the troubleshooter and got it to install but running it (and just before "NetMeeting has been installed successfully."), it returns this error:

conf.exe - Entry Point Not Found

The procedure entry point ASN1PERDecZeroTableCharStringNoAlloc could not be located in the dynamic link library MSASN1.dll.

I noticed that in Windows XP MSASN1.dll is located in %SystemRoot%\system32\dllcache so I thought if I copy MSASN1.dll from Windows XP to it's equivalent folder in Windows 7 it might work, does anyone know he equivalent folder? Then again I tried removing MSASN1.dll from it's folder in Windows XP and NetMeeting still ran so maybe not but it's worth a try.

Edit: The reason I don't want to use a virtual machine is because I wan't to use remote desktop sharing to connect from Windows 2000 to Windows 7 and vice versa, if I used a VM I would only be able to connect to the guest Os within Windows 7 rather than Windows 7 its self, and, virtual machines take to long to stat especiually just to run one program.

Since the dll is a 32-bit file I would put it in the 32-bit WoW64 System32 folder. Why are you against using a virtual machine, that would be the correct way, to run an unsupported program like this. – Ramhound Dec 4 '12 at 12:18
    
I can't find a WoW64 folder (my computer's 32 bit by the way), although I did find a wow32.dll. I'm against using a virtual machine because 1. they take too long to start and 2. because I want to use NetMeetings remote desktop sharing feature and if a ran it in a VM I would only be able to connect to the guest OS from the other computer rather than the host OS. – 5ives Dec 4 '12 at 18:57
    
That is helpful information. So just put the file in System32 in that case. Windows 7 replaced NetMeetings I am sure, I would use that instead, sadly you might have to go the route of a third-party application if you want to support Windows 2000 which isn't support by Microsoft. – Ramhound Dec 4 '12 at 19:22
    
Any reason why you can't use TeamViewer, UltraVNC, LogMeIn or similar? – Karan Dec 5 '12 at 0:16
