Just tried the new version and it fixed my mini-pac/pc setup.
I have a dell 4550 that would not recognize the minipac after reboot/shutdown if I made any changes to the button layouts through Winipac. Basically I'd have to do the registry fix every time I changed the button config, and this wasn't a problem for me since I wasn't planning on any on-the-fly changes, not yet anyways.
But now after uninstalling the old version and installing the new I can configure the button layout and it will recognize the minipac and all changes on reboot/startup. Perhaps I didn't follow the Winipac installation instructions (I left everything plugged in) but my 2 Ultrastiks stopped working on reboot/restart after installing the new version, and wouldn't work in mamewah unless I first used the Ultramap software. However, uninstalling the 2 unidentified HID's under Device Manager and then hitting "scan for hardware changes" on that directory fixed that and now
everything is working fine
