Adobe PDF preview handler 64-bit fix
Posted in Adobe
About the issue respectively about the fix
- The fix should only be applied to 64-bit versions of Windows that have Adobe Reader installed. Don’t apply the fix to 32-bit versions of Windows. If you’re not sure what you have use Start -> Control Panel -> System and Security -> System and look at the reported system type.
- You will need Administrator access to apply the fix.
- You may need to re-apply the fix if you update/re-install Adobe Reader, unless Adobe get around to fixing their installer.
- What the fix does is explicitly documented in Microsoft’s guidelines on Registering preview handlers so it shouldn’t cause any problems.
Installing the fix
Create a file called AdobePreviewHandler_x64Fix.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193}]
"AppID"="{534A1E02-D58F-44f0-B58B-36CBED287C7C}"
Copy/Paste the above lines into the .reg file and double-click it afterwards. This will correct the necessary values in the Windows registry. Please consider, a reboot is required for the changes to take effect.
