In installed my licensed copy of mach2 software on my shop computer that is connected to my mill and that is
working OK. Then I decided I would like to also install it on my office
computer so I could use it offline to sanity check .NC programs generated by my
CAM software. When I installed it I opted to NOT install the driver
because the office computer already uses the parallel port and I didn't
want to generate any conflicts.  It installed OK, but if I do an "about mach2"
form the help menu it says it is running in the demo mode. I didn't
think much about this until this evening when I found out that as
installed it is limiting the length of programs I want to test to just
under 1000 lines. Does anyone know how to get around this without
installing the driver? (which I am assuming is the problem). The license file is present in the program folder.

Possibly the license was corrupted. delete it and copy it over again, Make sure it looks just like this http://www.machsupport.com/forum/index.php?topic=301.msg1547#msg1547

Mine looks just like the example folder except, of course, my .exe is for mach2. I replace the files but still get the same result. Does the driver have to be installed to get out of the demo mode?

Installing the driver shouldnt cause any problems, I have Mach running on four computers and only one is hooked up to a machine, I dont have any problems with the driver causing conflicts. BTW the license will work just as well with Mach 3

Hi:

Only Mach3 version 2.0 does not require the driver for using as a simulator.
You can upgrage to that to use the system without a machine, in fact , no
license is required for that.
