Unable to update sysconfig of CCS 12.4

when I tried to open a project from new SDK, it prompted me to install the new sysconfig

clicking the "see", lead me to this page

2. Updating CCS 9.3.0 — SysConfig documentation

in the page it says I should install the sysconfig to 

 <root>/ccs/utils/sysconfig

however, i only have " <root>/ccs/utils/sysconfig_1.17.0"

for me the root is C:\ti\ccs1240\

I tried 3 methods, all end up with the same update required page

1. install the new sysconfig directly to  " <root>/ccs/utils/sysconfig_1.17.0"

2.  rename" <root>/ccs/utils/sysconfig_1.17.0", to  " <root>/ccs/utils/sysconfig_1.17.0_bakcup__",

create a new folder called,  " <root>/ccs/utils/sysconfig_1.18.0", and install inside 

3.install sysconfig to c/ti/

I am using CCS12.4
