Hi,
with Mach4 each PC that runs it must be individually licensed using the unique PCID number.
Note that there are certain activities that change a PCs PCID, and once the PCID has changed Mach4 will become un-licensed on
that PC. If you install a new Windows OS or refresh a corrupted version of the same Windows OS both of these will
change the PCID.
A Mach4Hobby license allows up to five PCs to use the one purchased license. You could have both your office PC AND your
machine PC fully licensed without problem.
Should a PC blow up or otherwise be destroyed you can, using the on-line license management system, release the license
for the faulty PC and get a new license issued for the new replacement PC. You are allowed up to seven such license transactions
in a two year period.
All-in-all Mach4Hobby licensing is pretty generous and will allow a hobby user full access to his/her purchased software
WITHOUT being the open slather type licensing of Mach3 which resulted in so many pirate copies.
