We have 2 types of software upgrades.

2. Major Upgrades

Minor Upgrades
Consist of improvements we make to our software to do some or all of the following:

Install new features to make the software do more.
Fix minor bugs
Optimize software to run faster
Optimize software to be smaller
Minor upgrades are free

Major upgrades

Are upgrades that are out of our control The only major upgrade we have made is to rewrite our software to work with Windows Vista and Windows 7.

Major upgrades are not free

Note::
Since 2016 all upgrades have been free until the arrival of Vista-Win7 & Win8.
This caused a total rewrite of our software
We do not foresee any upgrades that are not free.
