SYMPTOM
When a new µVision project is created with Project - New µVision Project... and a project is already loaded, it is possible that µVision reports the error Encountered an improper argument under some circumstances for specific microcontrollers. Under Windows XP it is even possible that µVision crashes in this situation.

CAUSE
There was an issue in µVision version 5.14.2.0 which has been identified and fixed.

RESOLUTION
Download the attached file and extract it to the folder C:\Keil_v5\UV4. If you have installed PK51 to a different folder, you need to adapt the path accordingly. The file UV4.exe is replaced with version 5.14.2.1.

PK51 versions later than 9.54a will include this µVision update.
