John,
I just upgraded my PC to W10 and have run into the same issue.? Also noticed a similar behavior on later updates to W7.? Seems for security reasons Microsoft is trying to prevent programs from writing any kind of variable data into their install directory under Program Files or Program Files(x86) once the application is installed.? I even had trouble on W10 placing a file directly under C:\.? think for older programs that did write to these locations they have added some means of "sand boxing" the variable (post post installation) date off to this? AppData\Local\VirtualStore location.?? Sort of makes sense now that most new apps get cryptographic signatures and get verified before being placed in a spot that gets launched.? I would install mach directly under C:\Mach3.??? In switching form W7 to W10 I had a number of old programs with similar behavior and just decided to make a directory called C:\MyProgram Files and put those programs there.
I still have my? BP bill running on a Windows 2000 installation.? --No updates, no internet connection just works.?? Doubt I could get it connected to the internet with out HTTPS support.
Good luck? Craig
