I was able to install this in Windows 10 by manually extracting the "exe" file, and running it as an "administrator" I saved the exe file to my desk top. It seems to work fine. I have used this gem for over 10 years, and will always be grateful to the developer.
I cannot install Radiation Decay v.4 on Windows 10.
The message is the following:
"Unable to save file:
The system cannot find the path specified."
Been using Rad Decay for a long time. Would love to see it made into an Android app so I can have it on my smartphone. No longer have PDA and not at the computer all the time. Need in the field. Great program, keep up the good work.
