This application has failed to start because winmm.dll was not found. Re-installing the application may fix this problem

im having a similar problem with winnmm.dll bringing up error messages when i try to open several programs or download from the internet.

I tried the first suggestion of regsvr32 winmm.dll but it brough up this message:

the module winmm.dll was loaded but the entry point DLLregisterServer was not found.

Make sure that winmm.dll is a valid dll or ocx file and try again.

I also tried the scannow and a similar reply, that errors had been found but were not fixed.

HELP!! :(

Have you tried to reregister the dll?  To do this:

Go to Start and type in "cmd" (without the quotes), then hold down Ctrl and Shift while pressing Enter.  This will open an elevated (Run as administrator) Command Prompt.

In the black Command Prompt window type "regsvr32 winmm.dll" (without the quotes) and press Enter

Then try to open Media Player.

If that doesn't work, then (in the elevated Command Prompt) type "sfc.exe /scannow" (without the quotes) and press Enter.

Let us know what it says when it finishes.

they said that" you must be an administrator running a console session in order in order to use sfc utility."

but still i see no change, still winmm.dll is still missing.

 

In the black Command Prompt window type "regsvr32 winmm.dll" (without the quotes) and press Enter

you can't register this DLL this way.

The sfc way is correct.

@vimoj

if you can get the DLL back with sfc /scannow extract the DLL from your Windows DVD:

and put the DLL into your system32 folder.

I tried to register and an error window pops up saying" The module winmm.dll failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found."

So i did the sfc.exe/scannow. then it showed verification phase of system scan. and stopped at verification 25% complete. said windows resource protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\wINDOWS\Logs\CBS\CBS.log

kindly help me to proceed further.
