Windows Process Activation Service is not a valid Win32 application.

Question

_{Friday, April 21, 2017 8:20 PM}

I started having an issue when starting the World Wide Web Publishing Service on my Windows 10 development workstation. When I try to start the service I get the following message:

The World Wide Web Publishing Service service depends on the Windows Process Activation Service service which failed to start because of the following error: World Wide Web Publishing Service is not a valid Win32 application.

If I look in the Event Viewer, I see another message for the Windows Process Activation Service on which the World Wide Web Publishing Service depends:

The Windows Process Activation Service service terminated with the following error: Windows Process Activation Service is not a valid Win32 application.

If I try to start the Windows Process Activation Service from the Services app, I get the following message in a dialog box:

Windows could not start the Windows Process Activation Service service on Local Computer: Error 193: 0xc1

Any help would be appreciated.

Thanks in advance.

You may check this: https://www.mindtimebackup.eu/knowledgebase/480307-Cannot-start-the-service-on-local-computer-Error-1930xc1

Please make sure there is no file Program.* on the system drive and no file Common.* in the Program Files folder.

You may run sfc /scannow as well to make sure the executables are not damaged.
