How to unregister 32-bit Indesign.exe

I am unable to use the full functionality of 32 bit and 64 bit InDesign CC application, when consulted Adobe they told Application uses same CLSID for both 32 and 64 bit, hence requested to uninstall 32 bit from add or remove programs which will unregister 32 bit CLSID registeries.

So we want this un-installation to be silent and we tired with diff. switchs from adobe blog which in end gives UI prompts, is there a way where we can uninstall the 32 Bit application silently using creative tool or PDapp.exe ?

Please suggest.
