Not possible to install or uninstall PG5!

After a crash of installshield, we can sometimes no more install or uninstall PG5 version.

When this happens, it is a big problem. It can only be solved by deleting the following windows registery keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{XXXXXXXXXXXXXXXXXXXXXXXXX}

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\InstallShield Uninstall Information\{XXXXXXXXXXXXXXXXXXXXXXXXX}

HKEY_CLASSES_ROOT\Installer\Products\yyy

and the next directory:

C:\Program Files\InstallShield Installation Information\{yyyyyyyyyyyyyyyyyyyyyyyy}

YYYY = product code

If PG5 is the version SP1.4.xxx, the PG5 ID code number {XXXXXXXXXXXXXXXXXXXXXXXXX} is: 82B3E307-BDE0-425A-8AF1-7DC6A7C392C1

If PG5 is the version SP1.4.xxx, the PG5 product code yyy is:703E3B280EDBA524A81FD76C7A3C291C
