I downloaded and installed MDK-ARM Version 5.43a. I started uVision and checked the license manger File > License Management.
But I cant see a "User-Based License tab" in it.
This is my UVision version information.
Why is that tab not available for me ?
I don't know any reason why you don't see the tab 'User-Based License' in the µVision dialog 'License Management'. Can you please uninstall and re-install the MDK 5,43a. Please also download the MDK 5.43a installer again, just in case the download file was incomplete.
