Windows Media Player 11 install problems

I had a pretty tricky problem tring to install Windows Media Player 11 onto a couple of clients recently. Basically it kept failing, with the error code 0xc0000005 in the %systemroot%\wmsetup.log. To troubleshoot this, I extracted the setup files to a temp directory and tried to install each component separately to see what was causing the problem. Amongst the extracted files were a couple of exe's, umdf.exe and wmp11.exe. When I tried to run these I got the following errors every time. (extracted from the installer log file)


Hotfix started with following command line: /log:c:\temp\umdf.log

I tried all sorts of stuff after searching on Google, such as renaming Catroot2 dir, checking and resetting permissions on files and registry using the SubinACL tool and scripts as found here, but it didn't work.

I could have easily fixed the problem by reinstalling the system, but where's the fun in that, so I logged a call with MS PSS. After 1.5 weeks of trying various things, they sent me a link to the following www.support.microsoft.com/kb/822798. I tried the methods in order, the only one that worked for me was method 9, extracted from the support document...

To clear the temporary file and restart the hotfix installation or the service pack installation, follow these steps:
1. Delete all the tmp*.cat files in the following folders:%systemroot%\system32\CatRoot\{127D0A1D-4EF2-11D1-8608-00C04FC295EE} %systemroot%\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}
2. Delete all the kb*.cat files in the following folders:
%systemroot%\System32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}%systemroot%\System32\CatRoot\{127D0A1D-4EF2-11D1-8608-00C04FC295EE}
3. Delete all the oem*.* files from the %systemroot%\inf folder.
4.
At the command prompt, type the following commands. Press ENTER after each command.
net stop cryptsvc ren %systemroot%\System32\Catroot2 oldcatroot2net start cryptsvcexit
5. Restart the failed hotfix installation or service pack installation.


Bingo, worked like a dream :)
