After applying one of these updates...

 

 

Windows 10 Creators Update (shows version 1703 when running winver.exe, starting around April 12, 2017)

Windows 10 Fall Creators Update (shows version 1709 when running winver.exe, starting around October, 2017)

 

... attempts to run Windows Mobile Device Center fail with the message "This app isn't working correctly", or starts to run but hangs at the splash screen.

 

In Event Viewer, the Windows Application Event Log may show one or more of these errors:

 

Problem 1: "This app isn't working correctly"

Solution 1: In Programs and Features, uninstall (in this order) Windows Mobile Device Center Driver Update and Windows Mobile Device Center, then reinstall (see below for installer downloads).

 

Problem 2: WMDC hangs at splash screen

 

Do both parts of the solution.

 

Solution 2 part a: In the Services applet (services.msc):

Stop Windows Mobile-2003-based device connectivity.

Double-click on it.

On the Log On tab, set it to log on as Local System Account (don't check the box "Allow service to interact with desktop), then OK.

 

Stop Windows Mobile-based device connectivity.

Double-click on it.

On the Log On tab, set it to log on as Local System Account (don't check the box "Allow service to interact with desktop), then OK.

 

Start Windows Mobile-2003-based device connectivity.

Start Windows mobile-based device connectivity.

 

In Task Manager, end task on wmdc.exe and/or wmdcBase.exe. Windows Mobile Device Center should now run correctly.

 

Solution 2 part b: Start a Command Prompt as Administrator, then run these commands:
REG ADD HKLM\SYSTEM\CurrentControlSet\Services\RapiMgr /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WcesComm /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
