Re: opa11.dat - associated with Windows Media Player

Hi,

Control Panel/Folder Options/File types tab, simply delete the .dat file association. Those files, by the way, shouldn't have any associated programs as they can be used by many different programs.

As to the security tab, in a Pro system you must undo simple file sharing under Folder Options/View for it to show. In a Home system, you must restart in Safe mode and use the Administrator logon to see it. If you feel that you are somewhat technically proficient, you could also use cacls from a command prompt.

Hi -

I'm on an AMD64 desktop with Win XP Pro SP2. I've been trying to update MS Excel 2003 with the latest security fix KB923088. Getting a 1406 error about halfway through the update. On the MS site, among other things, Method 4 suggests checking your Office Activation datastore stored in OPA11.DAT. You are to pull up the properties *** and adjust some permission settings on the Security Tab.

When I navigate to OPA11.DAT, I see the file is associated with Windows Media Player 10 because it's icon is the typical round-multi-colored disc you'd see for a multimedia file and its type is listed as a "Video CD Movie" over in the right hand pane. In fact I just noticed as you'd expect that somehow all the .DAT files have that association. Back to OPA11, not only is the association messed up but the properties panel has NO Security Tab for me to open and adjust. I've got to figure out how to get that association changed back to whatever association (no association???) should be effective so I can reveal the security tab and change the permissions. I note too that my other older Win XP Pro PC has the same goofed up association.

Anyone know anything about this? I've Googled it and am coming up with a lot of entries but nothing specific on how to revert this association.
