Extract the archive, keep folder structure, import the example project via the .pdbx file into your TESSY project list.
Once you load the project you will be asked to restore the Database, confirm this.
Open the TEE and inspect the attributes 'Compiler Install Path' and 'System Root'.
If they do not match your own local installation of Keil V5 adjust them accordingly.
