All plugins have INVALID APPLICATION error

I just got a brand new Touchsmart 300z running Win7 x64 Home Premium. I set up Windows Media Center, and added Mediabrowser for better TV show support.

Mediabrowser sometimes behaves normally, other times it gives me an INVALID APPLICATION unable to launch Mediabrowser error. I usually don't get the error when I first launch Mediabrowser. I usually get it (only sometimes) when entering one of the media collections, trying to play a video (again, only *sometimes*), trying to save settings, etc. The crazy thing is, sometimes it works.

It does seem to consistently give me the error for some video files. For others it might give me the error *sometimes*. Sometimes I can play the file without problem, other times I get the error.

All files play correctly in native Media Center, in the Touchsmart software (which also doesn't support TV series collections very well), and WMP.

Thinking this might be a video-related problem, I also installed Heatwave, GameEx, and mcShoutcast. Heatwave also gives me this error -- SOMETIMES. mcShoutcast and GameEx seem to always give the error. For kicks I also tried TunerFreeMCE - always gives the error.

I have tried various things like manually deleting caches, changing permissions for the ProgramData folder for the plugin to allow everything from the user profile that I log in with to run Media Center... Nothing has worked.

Yet I can use the native Media Center capability for videos, music, Internet TV, etc.

Basically, the upshot is that NO PLUGINS WORK CORRECTLY. I suspect that it is at least partially due to x64, based on the fact that when others have had the same errors that could not be resolved using the normal fixes, they were x64 also. Seems like the 7RC had less trouble from what I have been reading...

I'm very frustrated, and am thinking of returning the s****y Touchsmart and building a Win7 32bit or Vista 32-bit box... Maybe using XBMC or something and skipping the tuner all together, though the husband would really like to watch live sports OTA.

Any insight would be appreciated.

Hi Kati and welcome

First and foremost, do you have a backup we can restore from?

Do you have the win 7 dvd?

What we are going to have to do is remove all the junk that is currently on the system. if you have a backup (which most ppl dont) it would be fairly easy.

If not and you have the win 7 dvd we can attempt a repair install

If you have a generic restore dvd instead of the win 7 dvd it gets just a bit more difficult.

So let us know wahts, what< and we can put something together

In the interim there is something you can do that doesnt have much risk and might help. Its called a system file check. It verifies and fixes your system files you can run that by typing cmd in search>right click and run as admin>SFC /SCANNOW

Let us know the results you may need to run it more than once.

I don't have the full disks - it came with it pre-installed. It has a restore partition. I will try to do what you suggest, and if that doesn't show anything, wipe the machine to see if it was a codec I installed or something... But it's weird that it would be a codec given that it's also a weather plugin that causes the error.
