Hi Polter,
from the scrrenshot it seems that you are starting the Uninstallation by executing
C:\HPBSM\Uninstall\<cersion>\setup.exe
(that's the path on my box)
or do you run
C:\Program Files\HP\HP BTO Software\Uninstall\HPBsm\setup.exe
(again that's the path on my box)
if you use the second one, give it a try with the first one,
of course both work fine in my case ...
Did you check the logfile at %TEMP%\HPBsm_9.20_HPOvInstaller.txt for any obvious issues?
In any case you can download the BSM Uninstallation tool from
BAC_00898 - BSM 9.2x Uninstall tool for Windows
and simply remove BSM from your system.
Greetings
Siggi
