CCS/TMS320F28035: C2000 v6.4.2 compiler issue

Part Number: TMS320F28035

Tool/software: Code Composer Studio

Hi team, 

When running CCS, there is an error for c2000 compiler. Could you please tell me how to solve this? The notice is shown below.

This project was created using a version of compiler that is not currently installed - 6.4.2 [C2000]. See 'Help > Install New Software' and select 'Code Generation Tools Updates' to check if this compiler is available through a CCS update.

After following the hint of the system to install new software, the project still can’t be compiled. I think the 6.4.2 is installed but it can't be used.

Thanks.
