i encountered this error when i was running an installation of visio 2007. after doing a search, i found this blog entry that described the same problem. i concur with scott hanselm. this is a really lousy error. the blog entry itself doesn’t describe how to track down the problem. however, in a comment, michael grier indicates exactly where to look. in summary, you want to do the following: navigate to %windor%\logs\cbs inside this directory, find the “cbs.log” file and open it from the bottom up, search for the “(F)” in my case, this is what i found. 2009-04-24 09:30:21, Error CSI 000000b3 (F) A previous transaction requested a reboot, so you cannot commit any transactions until you reboot. oh, so that’s all it is? i just needed to reboot and clear out the pending changes first.
