Microsoft Camera Codec Pack (16.0.0652.0621) - "Could not write value Progid to key" error - Windows 7 on Macbook/Boot camp

I am trying to install the new codec from Microsoft to allow me to browse/preview RAW files. I am running Windows 7 as administrator on a MacBook Pro with Book Camp. The error I get is

Could not write value Progid to key
 \software\microsoft\windows\currentversion\explorer\fileExts codec\.arw\userchoice
Verify that you have sufficient access to that key, or contact your support personnel

I used the x86 file on the site

Any ideas? 
what a PITA this was!!

1. go into HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts
2. right click on Permissions
3. click advanced
4. uncheck "include inheritable permissions..."
5. Click Remove
6. Click Add
7. Type in Everyone and press enter
8. Click the check for Full Control
9. Check "Replace all child object permissions..."
10. Click Yes
11. Click OK

12. Run the install again. it should go fine now
After it completes

do steps 1-3 again.
4.  check "include inheritable permissions..."
5. Check "Replace all child object permissions..."
6. Click Yes
7. Click Everyone in the top list
8. Click Remove
9. Click OK

That should be it. Hope it helps everyone and MS fixes the issue.
