Discussion/Resolution
You can find the most recent version of your product on each product's "Information and Downloads" page: On-Screen Takeoff/Digital Production Control and Quick Bid and on PlanSwift’s Installer Download Page.

Versions and Licenses
If the first two numbers are the same between your version and the version to which you are upgrading, your license does not need to be updated.
For example, if you were upgrading from On-Screen Takeoff 3.98.03 to 3.98.18, your current license would continue to work. However, if you were upgrading from 3.98 to 4.0, your company's licenses need to be updated before you can install the newer version.
