    Hey there. I'm having problems trying to get display drivers to work properly recently on my Envy 14 (I think it's a 1050ea).

    On start up this week I got a new error message saying mom.exe, which I think is the Catalyst Control Centre (CCC) program, couldn't start ... (0xc000007b). I googled it and I think a 0xc000007b error is something to do with x64 and x86 compatibility... (mom.exe file location on my computer is C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static). Something to do with it being a 32bit program but it has a lot of 64bit dependent dll/exe's(?). I was looking at this post:

    0xc000007b Error Solution « Madhat Alsoos

    ...and I got as far as the solution section, but didn't quite understand it. In their example, they are running a 32bit exe and they found a few x64 dll dependency, whereas I get hundreds from mom.exe. Not sure what to do. Should there be a x64 version of mom.exe? Something like that? Any help?

    So as a consequence of this, my graphics aren't working properly; I think it's stuck on Intel HD graphics, and running poorly at that. Configure Switchable Graphics/Graphics Properties both don't work... just does nothing.

    I tried system restore back to a point last week, but the same error comes up.

    I tried stripping all the graphics drivers back and starting again. I uninstalled both Intel HD and Radeon 5650 in Device Manager, did uninstall of all ATI software, cleared using CCleaner and Driver Fusion to get rid of it all. Restarted in safe mode, then reinstalled stock AMD HD graphics drivers (sp50656), AMD and Intel graphics drivers (sp48434), then 11-2_mobility_vista_win7_64_dd_ccc_ocl. ... same problems. I'm still stuck on integrated graphics.

    After that, I've tried reinstalling the chipset drivers along with the graphics drivers again. Same thing.

    Any thoughts?
