If you have multiple cognos planning servers, you need to take a look at all of them and make sure that the components listed in the cmplst.txt are the same for the planning pieces. Specifically, the machine running the CAC service is the machine that serves the rcp_install files, so you would want to make sure it's the same as all of your other machines (app servers, job servers, gateways, etc)
A couple of things:
1. Please forward a screenshot of the error you are receiving.
2. Always list the full version, especially in cases where you may have version issues. This just makes it less confusing for the rest of us.
