I have a PC with Windows 7 Pro. It runs Simply Accounting 2011 and ACT 2009.
This morning no one could network to it. There were error messages referring to WMI (and other things) in Eventvwr.
I did a system restore to 24 hours ago. Machine came up, but both ACT and Simply Accounting Connection Manager fail to run.
When I run Eventvwr, it gives an error, saying MMC Could Not Create The Snap-in. Running MMC and adding the snap-in results in an error too.
I ran a repair on .net framework 4 Client Profile (the only .net stuff that was there) and no difference.
