@Joe_Sabo I downloaded Bill’s weekly DT build… so its current as of last night… I made a sort of portable version so you can just download the zip file and unzip it in your downloads folder or to a usb and then run using the batch file I put in the darktable directory… THe batch file simply points DT ie darktable.exe to use a config folder created within that program directory… so nothing is going on your system or into your current install…
Give this a try and see if it works or the same error…
So you have nothing to install. Just unzip and run…
