Visual Studio Team System 2008 Team Foundation Server Power Tools Oct ‘08 released. The new setup now installs for "all users" rather than just the current user. This was necessary because the Windows Shell Extension can only be installed for "all users". That's not really an improvement, just a change 🙂 The improvement is that the setup will now automatically uninstall previous Power Tool versions (including Dec '07, Mar '08 and Jul '08). This will eliminate one step when updating your Power Tools builds. One complication comes with the change to "all users" install. If you've installed previous versions using your user account and you install the Oct '08 release with the same user account, everything will work. However, if you installed the previous version with a different account than the one you install the Oct '08 release with, it will not work. You will need to log in to that account and uninstall the previous version. We had serveral MVPs hit issues with this where they had previous installs on other user accounts and had forgotten about it.
Oh, and one more thing I want to point out - the Power Tools can be installed and run on 64-bit clients. This includes the Windows Shell Extension (which means the Power Tools include both 32 and 64-bit versions of that component).
