I was hit by the problem after installing msWindows 2008 (standard, 32 bits) with SP2. After install it needed 64 upates, no problems jet. After the next reboot, there where 8 updates after which the problem arises. Fortunately the above routine suited my needs.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10112505" width="1" height="1">http://blogs.msdn.com/b/smondal/archive/2010/11/29/mmc-could-not-create-the-snap-in.aspx#10105353Wed, 15 Dec 2010 14:47:27 GMT91d46819-8472-40ad-a661-2c78acb4018c:10105353Steve<p>Thanks - just the ticket to solve my problem. &nbsp;</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10105353" width="1" height="1">
