I recently had to re-installl XP Media Centre edition to my computer.
Each time run Media Centre I get an error:

MEDIA CENTRE MEDIA STATUS AGGREGATOR SERVICE
Error SIgnature
Appname: ehmsas.exe

I am guessing the signature on the file is invalid, but not sure why or what to do ?

the file EHMSAS.EXE is found in C:\WINDOWS\EHOME

I attach a screenshot of error
Any help appreciated please.

If you wish to use ATI Catalyst Media Center on Windows XP Media Center Edition you may need to disable any specific MCE services running that may be locking down the tuners.

To do so, try the following:

1) Start Windows Task Manager 

2) Click the Processes tab

3) Right click and select end Process for any entry starting with eh such as ehmsas.exe, ehsched.exe, ehrecvr.exe and ehtray.exe.

Once thats done the tuner(s) should be free for other applications to use.

If you have an ATI graphics card this might be usefull... here is a link to the source (http://forums.hexus.net/showthread.php?t=92864)

OR
Cause:

A singular cause has not been identified, but it is mostly seen on systems with third-party software has been installed.


Solution:

Close out of Media Center, and Go to START > MY COMPUTER
Navigate to C:\windows\eHome\
In the address bar, type in CMD to open the command prompt

First, type in: ehmsas.exe /unregServer , and hit ENTER
Then, type: ehmsas.exe /regserver , and hit ENTER
Restart Media Center. The issue should be resolved.



If the symptom persists, do the following to re-register all MCE components:


Close out of Media Center, and Go to START > MY COMPUTER
Navigate to C:\windows\eHome\
In the address bar, type in CMD to open the command prompt, and then enter in each of the following, and then hit ENTER at the end of each line:
regsvr32.exe atl.dll
ehSched /unregServer
ehSched /service
ehRecvr /unregServer
ehRecvr /service
ehRec.exe /unregServer
ehRec.exe /regserver
ehmsas.exe /unregServer
ehmsas.exe /regserver

After completion, close the CMD window, and restart Media Center

None of the suggestions worked, I  finally removed the VFD panel drivers and it now seems to work.

Thanks
