Before Clarity r12.0.6, XOG Client can be downloaded via Admintool -> Client Download in the main menu -> Window Installer. In the installation process you can specify a different path. It is, however, always installed to C:\Program Files\CA\Clarity\CA Clarity XOG.
Steps to Recreate:
Expected Results: XOG client is installed to where you specified.
Actual Result: XOG client is installed to C:\Program Files\CA\Clarity\CA Clarity XOG.
From Client Downloads (XML Open Gateway Client), download and extract xogclient.zip to your preferred directory.
This issue has been documented as CLRT-25721 and it is fixed in r12.0.6.
