Component ‘RICHTX32.OCX’ or one of its dependencies not correctly registered: a file is missing or invalid.

When you run an application created in Visual Basic 6.0,  you get the above error message and your program terminates.

Thisis because your program uses Rich TextBox ActiveX Control (RichTx32.ocx), which is not included in the ActiveX file in the setup package.

To resolve the problem, download the RickTx32.ocx file and copy it to the Windows\System32 folder.

Remember that the VB6 run-time distribution package from Microsoft does not include the RichTx32.ocx ActiveX Control.

If you still receive the error, you need register the RichTx32.ocx module.

Go to  Start-> Run.

You’ll get a message DllRegisterServer in C:\WINDOWS\system32\RICHTX32.OCX succeeded. once registration is complete. Now your program will work without getting this error.

If you know the name of a process to kill, enter the following command from a command prompt to end it:

taskkill /IM application.exe

This will ask for confirmation to savw if there are unsaved changes, before terminating the process. To kill the same process by force, add the /F option to the command line. With the /F option, it will terminate all matching processes without confirmation.

To kill a single instance of a process, specify its process id (PID). eg:- if the  process to terminate has a PID of 420, use the following command to kill it:

taskkill /PID 420
