I have a company license to use Mathcad prime version 10. I provided license server name and port number. But when I open a file, it shows me to run this feature you need to upgrade to full license. There is a message: "This is a premium feature. To use this and other premium features, please upgrade to a full license using the upgrade button." When I try to upgrade the license, it directs me to purchase the feature.
Other coworker does not need to upgrade to use the feature. Please let me know how to fix the problem. We are in different time zones.
Solved! Go to Solution.
