Help - MCX upgrade failed, now MCX-PC software install fails

I have a Linksys MCX which worked fine for months with my Dell MCE 2005
(running Norton Internet Security 2005) until I tried to do the MCX firmware
upgrade (wirelessly) which failed part way thru. After this, all
communication with the MCX was lost. Resetting the MCX did not help so I
tried to uninstall and reinstall the MCX PC software. Now the software will
not install and fails with:

"/Setup Error

The setup for the Media Center Extender was not successful. Please try
the installation again, or contact your hardware manufacturer for
assistance."

In Event Viewer (Application) it reports:

"Product: Media Center Extender -- Error 1904. Module
C:\WINDOWS\eHome\MRProxy.dll failed to register. HRESULT -2147024770.
Contact your support personnel."

On power-up, the MCX sees my wireless network and retrieves the SSID with
excellent signal strength and gives the setup key so it's not a network level
problem (I've also tried this with a wired connection). I've tried manually
registering the DLL with regsvr32 and got

"DllRegisterServer in C:\linksys\mrproxy.dll failed.
Return code was 0x8007007e"

I've tried unregistering it and deleting all instances of MRProxy and tried
to reinstall, I've tried system restore, I've run "sfc /scannow" and
"depends.exe" looking for something/anything, all with no luck. I've gone
thru hell with Linksys tech support who effectively washed their hands of it
and said it is a MS problem.

If anybody has any ideas I'd sure appreciate hearing them. My frustration
level is off the scale. Thanks.

 

Just as a test, click Start, Run and enter REGEDIT Go to key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\RNG

Right click the RNG sub key and select Permissions. Ensure that Administrators has Full control. You may also want to try adding your specific username to the list and giving it full control.

If that doesn't resolve your problem, try REGSVR32 ATL.DLL

 

Doug, the "REGSVR32 ATL.DLL" did the trick. The software installed OK and
everything is back up and running.

I'm thrilled...many thanks for the help!

 

You're welcome
