I have not used the program in Windows 10 as of yet. That being said, I still keep ASA running on my older PC using 64 bit versions of windows software.
The crack software listed in the original Russian downloaded versions of ASA, was the key to getting the program to work. As long as the program wasn't auto-updating (which I think was taken out of the program likely to keep it working as long as mine has), the crack update feature that you re-direct the Registry Key with, is yeah, the key to making it stick. It has been years since I installed the programs on my older pc and I would have to try and make this work on my newer PC with Windows 10.
New links have come to light that are Russian based, but provide updated versions of the ASA softare.

You can also get Mitsubishi Flat Rate Manual to use to your advantage when estimating time to do a simple repair or for major work on the exterior. I have just installed the Flat Rate Labor Time Guide using Windows 10, and it is up and running as intended. Very rudimentary and will take some time to familiarize with, but should do the trick. I always give up a day when I want to do something basic on my car, as so many little steps on taken along the way to care for fit and finish and or anticipating extra parts required to complete the task without having to step away from the job, mid task. If looking to quote a labor time for major vehicle repair in the future - like a wrinkled rear end due to being hit from behind - you now have the tools to use to prove what labor time is a bare minimum, assuming OEM parts are used to do the repair - if this writes off a car or provides for a higher labor payout with no repair performed (IE a cheque from your insurances company in lieu of repair this is the information you need as provided by the manufacturer!). I installed the 2007 version as I was hoping earlier models were not dropped, as in later 80's/early 90's platforms.
