µVISION: Updating Serial Number After Renewing

Information in this article applies to:

• µVision Version 2.34

QUESTION

I have just renewed my support contract and received a new serial number. However, the µVision IDE still shows my old serial number. I verified this by going to Help -> About µVision, and looking at the 'Serial Number:' section. 

How can I update this serial number with the new one I just received?

ANSWER

The information from the Help-> About µVision window is pulled from a *.ini file. You can find this in the \KEIL\TOOLS.INI file.

After opening the TOOLS.INI file, look for the Compiler you are using in brackets. For example, [C51] list all of the relevant details for C51.

Look for a line SN=XXXXX-XXXXX-XXXXX where XXXXX-XXXXX-XXXXX is your old serial number.

Enter your new serial number here. Now when you need your newest serial number, you can conveniently read it from Help -> About µVision.
