I was helping a user out today who had issues opening a .doc Word file in MS Word 2007. The user was getting the following error.
“You are attempting to open a file that was created in an earlier version of Microsoft Office. This file type is blocked from opening in this version by your registry policy setting.”
It appears the document he was opening was probably created in a very old version (pre-97) of Word, so the standard Compatability Mode in Word 2007 wasn’t picking it up. The easiest way to allow these older .doc files to open in Word 2007 is to follow the steps below. If you are new to editing the registry, you may want to back it up first. You should also make sure that any Office applications are closed before starting this process.
- Go to Start, then Run, then type regedit in the Open box, and then hit Enter.
- Locate HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Word\Security\FileOpenBlock
- If this registry key exists, skip to step 4. If this registry key does not exist, you will have to create it. From the HKEY_CURRENT_USER\Software\Policies\Microsoft\Office key, right click and create a new key named 12.0, then from that create a new key named Word, and so forth until you have the registry listed in step 2.
- Once you have selected/created the subkey from step 2, right click on it and select new DWORD Value.
- On the new DWORD Value, rename New Value #1 to FilesBeforeVersion.
- Right-click on FilesBeforeVersion, and click Modify.
- Make sure that the Value data box is populated with a 0, and hit OK.
- Exit the Registry Editor and try to open the problem file, it should now open in Compatibility Mode.
