Microsoft Word 2007 / 2010
After installing MS Office 2007 file conversion tools
Still get "error while opening file"
I recently have been hit by this problem several times. I am using MS Office 2003, and
people are sending me files from Office 2007 (or 2010). I downloaded and installed the
Microsoft conversion tools
from the MS web site.
After Googling a bit, I finally found
a useful suggestion.
You need to re-register the OLE32.DLL file, as described in
this article from Microsoft.
- Close any applications that are running.
- Open an elevated command prompt. To do this, click Start , click All Programs , click Accessories , right-click Command Prompt , and then click Run as administrator . If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
- Type the following:
regsvr32 %SystemRoot%\system32\ole32.dll and then click OK.
- When you receive the message "DllRegisterServer in ole32.dll succeeded", click OK.
