I solve my registration problem. The reason for not functioning was, that the registration file must be located localy.
In the meentime a have another problem. We have workstation where different users can login. The advansys product is every time deinstalled when a second user is login to the workstation.
I suppose that happens because settings are writen to HKCU. Can you tell me how can I handle the problem for workstations used by multiple users?
