Windows Live writer startup error: unable to locate the program Input Point isthreaddesktopcomposited on the Dynamic Link Library user32.dll

Today, Windows Live writer is installed and run. The error message is as follows:

View the event Probe:

Pop-up application: windowslivewriter.exe-unable to find the entry: unable to locate the program Input Point isthreaddesktopcomposited on the Dynamic Link Library user32.dll.

No way, you have to look at user32.dll first:

My user32.dll version is 5.1.2600.3099. The above shows all function entries. Obviously, there is no isthreaddesktopcomposited, so it is strange to see this error. So it seems that the DLL loaded by Windows Live writer should not use this function of user32.dll. In this way, you must check the DLL loading process to determine the cause:

Using the VC tool, we found c: \ windows \ system32 \ mprapi. DLL calls the isthreaddesktopcomposited function in user32.dll, but this function is not found in user32.dll of XP, so an error occurs.

Solution:

Rename mprapi. dll, such as mprapi. dll. Bak.

Run again to solve the problem.
