SAP GUI 720 PL4: "Failed to load administrator rule file"

Hi all

we are up to install SAP GUI 720 PL4 compilation (dated 15.12.2010) and are getting the following information when opening either LogOn Pad or Configuration Pad:

"Failed to load administrator rule file. Check your installation".

We did re-install the package several times, did delete the whole SAP folder afterwards as well etc. but without any effect.

We also installed with local admin-account.

What we couuld further see is that in "SAP GUI Security" pad there are no standard SAP security rules available like mentioned in the config guide!

So are we anything missing?

Your help is kindly appreciated.

Best regards
