I just upgraded from 4.8.5 to 4.9.0 and again to 4.9.1. Upgrade went fine, all info is intact, the snap-in works fine, for the most part.
I do, however, get error “Run-time error ‘35601’: Element not found” whenever I click on one of the column headers to sort the devices.
This does not happen everywhere in the MMC. In package/update/rapport/configuration Manager I can sort by column. Eventually, if I leave the error up for around a minute, I get another error: “DisplayError: 429 ActiveX component can’t create object.”
I turned off IE ESC to no avail, and also tried unregistering/registering the rapport mmc dll file.
