keil uvision Could not open file C:\Keil_v5\ARM\RV31\Lib\RTX_CM1.LIB: No such file or directory

[ETale.1]

hi experts

i generated a project using cubemx and started programming using keil uvision 5.28 IDE and my program used RTOS 

after days of programming and testing I faced some unusual problems that made me think that my keil had issues and caused those problems, then I uninstalled the keil and installed a newer version ( 5.30 ) but this time I got the "keil uvision Could not open file C:\Keil_v5\ARM\RV31\Lib\RTX_CM1.LIB: No such file or directory" erro in build output and i could not find a solution by searchin the internet , I would be very thankfull if you help me !

thanks for your time

What on earth is it using the CM1 version for?

After uV 5.15 or so, the RTX stuff moved under the packs, as I recall

C:\Keil5xx\Arm\Packs\ARM\CMSIS\5.6.0\CMSIS\RTOS2\RTX\Library\ARM\RTX_CM3.lib

I don't know why and this stuff are a little confusing for me

thanks clive !!! sorry to ask but I'm new in stm32 programming how can I change the path to the path you mentioned?
