Hello all,
I am sorry that some are having problems. I have been using this program for several years now and find it invaluable as I repair old machinery for a hobby and come across threads that most don't know exist. I posted in the spirit of this site as I believe that the program will be of use to many.
To Murph1090, have a look at what steamingbill has written and also my reply to Y-Geo. I have no idea what a Harbor Freight #44859 is and when you say "no backgear" ??? If you do not have a gear train to the leadscrew why have you got extra gears?
azbrewer something that had me wondering what I was doing wrong for many hours when I moved up from XP was that now there is a default with downloaded programs that means you have right click on the program, properties and at the bottom click on 'unblock' and then 'apply'. This applies to just about every program and NO PROGRAM will install until this is done.
I hope that the aboves answears,( mine and steamingbill's), will help resolve any issues.
Best regards,
Barry.
