Just to clear something up what version of Microstudio are you using?
You need to do the removal through the Microstudio Setup program, not the Add or Remove Programs in the control panel.
Doing a search for Microstudio doens cleareverything out, because not all the files used with/by Microstudio have Microstudio in the name. So you need to go to the locations with Windows Explorer directly and not in search and delete as I said.
Did you burn the Setup to disc or order it that way from MTU? If you did then try downloading it again from MTU and use the new download to install.
