I wanted to un-install uVision 3 for 4 because I found that it did not have support for MCBSTM32. The problem is that I cannot find ways to un-install it before installing uVision4. Pls advise. Thanks in advance
Maybe you should keep uVision 3, in case you have projects using that version. Switching to a newer version of the tools for existing projects could lead to a lot of work trying to retest/qualify the old code.
