Force uninstall in System Context for Applications

Hi

I create Applications script based. in the deployment type I set the installation behavior to install for system.

when I try to uninstall a program from the Software Center I get the following error:

Executing Command line: "blablabla" /SILENT with user context

ScriptHandler::EnforceApp failed (0x8007010b).

AppProvider::EnforceApp - Failed to invoke EnforceApp on Application handler(0x8007010b).

CommenceEnforcement failed with error 0x8007010b.

Method CommenceEnforcement failed with error code 8007010B

++++++ Failed to enforce app. Error 0x8007010b. ++++++

how come the uninstall command runs with user context and not with system context?!

is it even possible to modify it?

thanks for the help
