Unable to use the debugger in Auto Dev Kit due to an expired license

Moved  from STM32 forum - this is not an STM32 question.


I am facing an issue with the Auto Dev Kit debugger. My previous license had expired (Hightec), and although I tried renewing it and even registered to get a new license, the debugger still does not work.

Additionally, I notice that the debugger and flash icons appear greyed out.

Could you please assist me in resolving this issue?

I have solved the issue, autodevkit works with free license and the error at the start confuses you with pro that you think is not installed, but actually its the free complier which is working. So to conclude we can can just ignore the pro compiler error.

This debugger licence management is fully in the hands of Hightec, nobody on this MCU forum can help with that.

They surely have a forum, helpdesk and support team as well.

Ok, but also I didn't get the answer for my 2nd question 

(Additionally, I notice that the debugger and flash icons appear greyed out.)

As you don't have a licence for the debugger, it doesn't seem unreasonable that its icons are greyed-out.

 

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Right, I thought that was self-explanatory.

If you lack the experience to deal with this issue, ask your direct supervisor for assistance.

Yes, I did that, but it's still greyed.

The board is connected?

The file is compiled?

I do not see why it should not work...

Wrong version of PLS?

Nothing depending from ST as far as I can see.
