Can I upgrade my subscription to unlock all options

And what is the difference, there is a copy for 58 dollars
And another 1500 dollars, thank you

Hello,

There is no upgrade, you can buy the license you need.

Regular license $58 is for single active installation for you or one of your clients.

Extended license $1500 is for multiple installation, if you want to built-up on the item or use it for multiple clients or multi-tenant or SaaS.

Thank you

Is the license permanent for life? Complete diseases have the license?

Yes, license are lifetime. What do you mean by `Complete diseases have the license?`?

Is there an annual subscription?

When purchasing the full version

Hello,

No, licenses are for lifetime, not subscription based. Each purchase comes with free support is for 6 months and it can be extended as you need.

Thank you
