You can upgrade your current ProCalX Desktop version easily in the help center. Clicking the help icon will open a panel on the right side of the screen where you can redownload the ‘ProCalX Desktop’.
After the download is complete, you will launch the ‘PCXDesktop.msix’. The installer will launch and you will have an option to ‘Update’ your current version.
This will apply the latest patch to your desktop application without the need of uninstalling first and reinstalling.
