I install the TMS FNC Core and the TMS FNC UI Pack in visual Studio code.
But after running my app the Tab and tree view is displaying the trial version "TTMSFNCTabSet Trial" I have paid license. how to activate already the generate license in visual studio code but is not working.
Did you download the full registered version after login on our website under Account / My Products?
Yes
I retested this here but I could not see a problem.
I can only suspect you still have old trial version files on your system.
I suggest to delete the entire TMS WEB Core install by deleting folder
C:\Users\<USERNAME>\.vscode\extensions\tmssoftware-tmswebcore-?.?.????
and then reinstall step by step and making sure you only use registered version distributions.
