I do have APC powershute business basic running. I stopped both services and retried with the same negative result. Below is a part of the backupinst.log refering to my attempt to repair the installation of BE after I stopped the APC services. Also the MISInstaller gives me an error code 1603 when I tried to install BE9.1 SP4 update last week. Today I am trying this from terminal server at a remote location and there is only a warning in event viewer.
