For ages I’ve been running Office 2007 on Vista x64 and now Windows 7 x64. Both suffer from Outlook not being able to preview PDF files. Providing the following error -
This file cannot be previewed because of an error with the following previewer:
PDF Preview Handler for Vista
To open this file in it’s own program, double-click it.
People have been installing other 3rd party tools to fix this problem, however here’s the perfect fix (it doesn’t even need a reboot).
To enable the preview of PDF files in 64-bit OSs, do the following:
1. Start the Registry Editor (Start – Run – Regedit.exe).
2. Move to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193}.
3. Change the AppID value to {534A1E02-D58F-44f0-B58B-36CBED287C7C}.
Or create a Registry file -
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193}]
“AppID”=”{534A1E02-D58F-44f0-B58B-36CBED287C7C}”
