I'd just confirm the steps you took. As far as I know, you need to do the following:
- Set your givex redemption servers IP (probably CAPS) in the custom content file in EMC for that site.
- Install givex on your redemption server(CAPS).
- Configure your givex.ini file on the server with the correct info specific to this location
- Deploy the givex cal package from EMC to your workstations
You may also want to try manually forcing your workstation to update:
Go into RegEdit → Micros → CAL
Manually change the version number of the package that was installed (XProcessor, etc) to force an update.
