1. What is the type and terms of the license?

The license is a subscription-based, single machine-locked license or floating license (Windows 64Bit machine).

• Single machine-locked license

Single machine-locked license is tied to the hardware on which it is first activated. In case of formatting of machine or change of OS to another supported one, you do not have to repurchase the license. You will only need to reactivate it.  A new license will have to be purchased if you switch to another device. This is the reason we are able to keep the cost low on this type of license. If you want more flexibility in working on different machines, you should consider buying a floating license (please review terms for details) or multiple licenses. 

• Floating license

The floating license can be ported to multiple machines. But it can remain active only on one machine at a time. To port it to another machine, you need to release the license from the first machine. This license is ideal if you are having two or more devices on which you work viz. office, home or on road. You can keep the license active on the machine which you plan to work on.

2. Can I shift my license to another machine?

Our licenses are only activated once for one and only one hardware. You won’t be able to transfer this license to any other machine for whatever reason (machine crash, hardware fault, etc.). You will have to purchase a new license if you want to run this plugin on any other machine.

3. How many users can install the software at a time if we purchase one network/floating License?

The floating license can be ported to multiple machines. But it can remain active only on one machine at a time. To port it to another machine, you need to release the license from the first machine.

4. What about future updates of plugins or our CAD software? Are they included? Do we need to buy again, if the plugin is updated or there is a new version?

• We provide free updates for a year from your purchase date.
• You can purchase an upgrade after a year if required. The upgrade price of each plugin is provided on the respective plugin page on our website. 
• If you don't want to update the version of your plugin, the old one will still work. 
• You can download the latest version from https://www.prototechsolutions.com/3d-cad-plugins/ and use the same key to get it working.
• The upgraded version of the plugin will work on the same machine for which the purchase was made earlier.
• Please contact us at support@prototechsolutions.com if you face any problem.

5. How will I receive the license?

• Your product activation key will be sent via email as soon as you complete the payment process.
• You may sometimes not get the invoice or license activation key immediately after your payment. There can be many reasons for it - some of them are as below:
  1. The transaction is still in process between various payment gateways. 
  2. Even though you might have got a confirmation of payment processed, we might not have received the payment.
  3. The email might have been blocked by your spam server. Also, please note that the invoice and license email will be sent to the email id associated with your PayPal/payment gateway.
