Hello Marc,
Upon further investigations, I think I have found a way in which you can install your driver, other than using the Repackager.
In order to achieve this, please follow our
"EXE(s) to MSI" article.
After doing so, please go to "Install Parameters" page and select the
"Limit to basic user interface (simple progress and error handling)". This way, the UI of our MSI wrapper will reduced.
Additionally, you can also uncheck the
"Register product with Windows Installer" option from
"Product Details" page. This way, the MSI wrapper will not be registered in Control Panel.
Hope this helps.
Best regards,
Catalin
