Driver Preinstallation not working on Windows 7

[IRTrans]

Hi all,
I do have a setup generated with IA9 that we are using for some time now.

In the meantime we also support Windows 7 including a signed Windows 7 USB Driver. This signed driver can be installed manually but not through DIFx. Installing the same Driver with the same setup does work on XP.

There are no error messages - the driver is simply not installed on Windows 7.

Are there any known problems with DIFx on Windows 7 ?

Thanks, Marcus
