After upgrade to lightroom 4.3, my canon 7D is not showing up in lens profile correction

Question

I think this happened after upgrading to lightroom 4.2, but I am not sure as I haven't used Lens profile correction in some time.
When I enable the "Enable profile corrections" checkbox in "lens corrections" The Make and model of the lens is recognized, but the profile field has only 2 optoins, "canon EOS 1D MK III" and "Adobe". It does not have any other options including the EOS 7D that I use. Tried uninstalling and installing again, that didn't help.
I found in the forum that for Win 7, lens profile is supposed to be stored in "C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0", in my case the LensProfiles directory does not exist. There is a CameraProfiles directory(C:\ProgramData\Adobe\CameraRaw\CameraProfiles).
How do I solve this?

There is nothing wrong with your lens profiles. 
The issue is that you are adjusting a JPG not a raw file.  When adjusting raw files the camera model is not listed with the profile because it doesn’t matter and all of them say Adobe as their source for Canon cameras at least, but when adjusting JPGs the camera may have done certain adjustments internally so it does matter and is why you see the wrong lens-distortion occurring when choosing the 5D Mark III profile with your 7D JPGs.
For the record, I have profiles in both the locations mentioned: under Program Files\...\CameraRaw and under ProgramData\...\Lightroom 4.x.  This makes sense because I have both Photoshop CS6 and Lightroom installed.  The ones under Lightroom are all dated 12/2012 while the ones under Camera Raw are mostly dated 2/2012 with some from 11/2012 and other dates.  The profiles are probably the same, but the Camera Raw ones retain the date of the original profile creation whereas the Lightroom ones all get updated to the same date.  Lens profiles can also be installed with the DNG Converter, although I'm not sure which of the two locations those install to.
