When you try to open the Winshuttle Excel Add-in you get an error message "License Checkout Error"
Solution 1 - This error usually occurs when the user is attempting to open the Winshuttle Excel add-in before activating the software. To resolve you will need to have the user activate the Winshuttle application directly from the desktop icon. After activating the license, the user should be able to access the Excel add-in without error.
Solution 2 - If the Winshuttle software is already activated and the user is still receiving this error, the user likely has both the developer and runner software installed. Having both applications installed can cause Excel to read the wrong add-in. To resolve you will need to confirm which application the user is licensed for. If the user has a developer license they will want to uninstall the runner software. If the user has a runner license they will want to uninstall the developer software.
