Setup says VS Integrated Shell 2010 ENU installed when uninstalled, Grrrr!!!

I came across a situation where i had to remove the Team Explorer version 2010 Beta1 from my machine. I have uninstalled it via Uninstall option from the Programs and Features. When i tried to install TFS 2010 RC Team Explorer setup it says “VS Integrated Shell 2010 ENU” exists and have to remove. I did the uninstallation and restarted the machine even. Nothing happened and when i ran the installation it prompts me again saying that “VS Integrated Shell 2010 ENU” already exists. I checked the Programs and Features and it was not there. :(

I was something like this :

finally found the solution.

simply run this command :

msiexec /uninstall {874D5E2B-AACE-303A-B3EC-2563E071473E}

lets we dig little bit deeper in to the above command.

Initially you have to to do is to use msiinv.exe (thanks to Aaron Stebner’s to exposing the tool) tool to see if MSI thinks the integrated shell is installed or not. So from that tool it will lists all the installed programs and under that list you can see this ghost “VS Integrated Shell 2010 shell ENU” still exists in the list.

what you have to do is just note down the Product Code and use the same code to execute the above command.
