Getif SNMP MIB Browser

http://www.wtcs.org/informant/getif.htm

I had a problem installing this in Windows 7, but was able to eventually get it to run.
The problem is with the Msflxgrd.ocx file which doesn't get registered in Windows 7.
This site provided some clues: http://www.ascentive.com/support/new/support_dll.phtml?dllname=Msflxgrd.ocx
And so did this site: http://social.answers.microsoft.com/Forums/en-US/w7repair/thread/471a9b26-88c1-4765-9417-bae27ff8fe3b
The manual process goes something like this:
Copy the Msflxgrd.ocx file to the windows\system32. That file can be found in the 'ascentive.com' link above. I also found this file in the sysWOW64 directory, but Windows 7 was giving me an error message saying it was not available.
Next, I did a right click on Start >> Accessories >> Command Prompt and selected 'Run as Administrator'.
Then I executed the following from the command line:
%systemroot%\SysWoW64\resvr32 \windows\sysWOW64\Msflxgrd.ocx
I had to run Getif as admin, but I expect changing permissions should be trivial.
