Error during update from version 12 to 13

ccude

Hi, our company is using teamviewer since version 6. We have many clients which are working just fine, but one computer has a problem: During the update process from version 12 to 13, I get the message "error launching installer". When I start UNINSTALL.EXE from the old teamvierver version 12, I get the same message. How can I wipe teamviewer from this computer, so I can install version 13? Claus-Christian Ude MEDLINQ
