LSH error on installation server: Could not install DS as a service

Hi

we set up an installation server some time ago. In the past all users had administrative privileges therefore no LSH was necessary. Currently we are upgrading from Windows XP to Windows 7 and the users won't be admins anymore. That's why LSH is necessary now.

I tried to set the LSH up, but when I confirmed the DS und IS data in the LSH configuration, the following error appeared:

Could not install DS as a service

The server provides SAP GUI 7.20 PL 8

The installer version is 8.6.1.72 (latest!?) and reffering to note 1587566 didn't result in any solution. A similar problem is mentioned in thread LSH on installation-server fails with "Could not start DS as a service" but it doesn't help me either.

Did anyone figure out similar problems with LSH or knows a workaround/fix?

Kind regards

Jann
