Metastorm 7.6 installation fails due to IDriver.exe error

Issue:

The installation aborts after starting "setup.exe". In the install log the line "1: GetInstallDriver, Can not find InstallDriver in ROT table, Return Code = 0x80004005" can be found which points to an InstallShield file.

Resolution:

1. Stop any installations and reboot the machine. This step is necessary because the BPM installation may have crashed and may still be holding system resources.
2. Go to c:\program files (x86)\common files, and rename or remove the InstallShield folder.
3. Retry the BPM installation, using "setup.exe" and running as administrator.
