Thanks for putting this together Reclaimer, and all those who helped.
One thing I might add to the install instructions is a suggestion to run 7Zip as admin. I had files unblocked and everything seemed to be working fine except it never completely unzipped one of the databases. Running as Admin solved it. Not sure if it's a Windows 10 quirk or just something about my laptop or I overlooked that in the instructions somehow
Also, for Step 10, there's a difference in phrasing between the instructions and the program. It didn't ask for a dealer ID, I can't recall what it actually said but I kinda assumed that meant the same thing as dealer ID
