Installation through Self-Service Portal asks for admin credentials

Installation through Self-Service Portal asks for admin credentials

HI,

I created a package like packagename.exe /SILENT. It was successfully added to to all users group and is shown on the clients in the self-service portal. When a User tries to install that package, UAC pops up asking for admin credentials. This is weird, because my understanding of this feature is,that software ist installed via agent, which has all the right it need to install software. Other packages do not require admin credentials. Any ideas?
