PDF previewer is not installed

Question

Hi guys,
I have a user who has Outlook 2010 installed (running from exchange server) on Win8, who cannot view PDF previews. Acrobat reader XI is installed (and recently acrobat XI pro) and she still cannot view previews, gets the error "PDF previewer is not
installed" 
Steps I have taken:
Uninstall/reinstall acrobat reader.
Open reader and accept user license.
Enable previews in the trust center.
 So far I have not used the reg edit fix that has been floating around, just because that fix is for the "pdf handler for vista" error, and this user has Win8, not sure if it will fix it.
And ideas or suggestions? I know this topic has been beaten to death but I can't find anything that works.

Hi,
Please go to File > Options > Trust Center > Trust Center Settings > Attachment Handling, click the button "Attachment and Document Previewers" and check if the "PDF Preview Handle" is listed there.
If it's not listed there and you are using a 64-bit Windows, you can try the following steps:
Note: Serious problems might occur if you modify the registry incorrectly. For added protection,
back up the registry before you modify it.
1. Open the Registry Editor.
2. Navigate to the following registry path:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193}
3. Add a String Value under the key:
Value name: AppID
Value type: REG_SZ
Value: {534A1E02-D58F-44f0-B58B-36CBED287C7C}
Please let me know the result.
Thanks,
