When attempting to view the Event Log on Vista workstations with PeachTree installed, the following error message is displayed:
MMC could not create the snap-in.
The snap-in might not have been installed correctly
Name: Event Viewer
We've heard that this error also occurs on Server 2008 machines as well. There's several reasons for this error, however on boxes with PeachTree installed, load .NET 3.5 SP1 or perform a repair installation from the Programs applet in the Control Panel.
