Just up graded my New HP Laptop from windows 8.1 to Windows10. Every thing seemed to go fine, system actually seemed to run much faster and all of my old programs worked even my old Oehler Ballistic Explorer program. Then I tried to run my QL program and it said to reinstall it. So I removed the original program from the machine, dug out my Disc and reinstalled it, it appeared that all of the files went in and it said setup is creating icons and then a message came up. Path/File error an unexpected setup error has occurred. Has anybody run into this problem, I hate to think I can't use a $150.00 program on my new computer.
