I get a Windows 10 error when executing SARMCM3.DLL in Keil V4.60. On the first debug session all works well, but when I quit debug, compile the project and resume debug UV4 is closed. Winodws log reports Exception Code 0xc0000005. When I run Keil V5.25 all works well.
In that case, you can contact Keil support direct.
