Installed Windows 10 and tried to install the driver smoothieware-usb-driver-v1.1.exe as administrator and as regular login and it errors out "This app can't run on your PC To find a version for your PC, check with the software publishers". Well this is why I'm an early adopter, hoping to get these kinds of things fleshed out. Any help would be great.
I'm not sure if this is related or not, but there have been numerous issues with USB communication in Windows 10. There were some major bugs reported all the way back with their developer builds many months ago, and as far as I can tell, none of them have been fixed. The issues affected COM port serial communication, and it would cause the serial driver to randomly stall for long periods of time. This obviously causes big problems during printing since an hour into your print, the serial driver would just stop functioning completely. Some people thought it might be related to the new energy savings stuff in Win10, but hard to know for sure.
There's a few threads on the microsoft site about as well as other places, so until they get it fixed, I'd probably try to avoid Windows 10 for USB serial stuff.
Try running it in Windows compatibility mode.
Here's the rub with running in Windows Compatibility mode in windows 10. Windows 10 doesn't have a compatibility mode. It does have Check Compatibility option. Read on the web about running virtual PC to solve compatibility issues. Can't download it from the Microsoft site using Chrome. When using Internet Explorer, IE has an option to show all (IE thinks some of the information on the Microsoft website isn't secure) After show all is selected, you can then download using IE. After that, Virtual PC won't run in windows 10. Yeee haaaa. Well, I'll just use a different computer for the printer. Gotta love it. It was a free upgrade.
