Installation error of "ThingWorx Trial Edition Installer" on windows 7

Hi,

can not install the package "ThingWorx Trial Edition Installer". At the end of the installation the installer reports an error:

"

Executing D:\twx\ThingWorxTrialEdition\win-installer/ThingWorxIndustrialConnectivity.exe /qn /e ACCEPT_EULA=YES
Script exit code: 1603

Script output:

Error running D:\twx\ThingWorxTrialEdition\win-installer/ThingWorxIndustrialConnectivity.exe /qn /e ACCEPT_EULA=YES: Program ended with an error exit code
There has been an error.

Anybody has an idea ?

Best Regards
