We’ve heard some reports from people who are upgrading to the Mar 2008 Power Tools that they have had problems uninstalling the Dec 2007 Power Tools (which you must do first). They get “error 1001” – a very useful error message a must admit. It makes me wonder what the other 1000 errors are
Anyway, working with a few customers, we have determined the cause of the problem – and the work around is easy.
Solution – Repair then Uninstall
Go to Control Panel, Add Remove Programs (or Programs and Features if you run Vista).
Select the Microsoft Team Foundation Server 2007 Power Tools – December 2007 release
Select the Repair option. Press next. Complete the repair.
After the above is finished, Attempt the uninstall (i.e. press the remove button)
Install the March 2008 Power Tools
Customer installed September 2007 Power Tools and December 2007 Power Tools on same machine
Customer uninstalls September 2007 Power Tools
Customer uninstalls December 2007 Power Tools (this fails with error 1001). The September uninstall removed things needed by the December 2007 uninstall.
Hopefully this will help you if you hit this problem. Let me know if you find other issues.
