When you run an application which was created in Visual Basic 6.0, the following error message may occur and the program terminates.
Component ‘RICHTX32.OCX’ or one of its dependencies not correctly registered: a file is missing or invalid.
This happens if the program uses Rich TextBox ActiveX Control (RichTx32.ocx), but does not include the ActiveX file in the setup package.
To resolve the problem, download RichTx32.zip. Unzip the archive and extract the file RichTx32.ocx to the Windows\System32 folder.
Note that the VB6 run-time distribution package from Microsoft does not include the RichTx32.ocx ActiveX Control.
Registering the OCX file
If you still receive the error, register the RichTx32.ocx module using the following command (from Start, Run dialog):
regsvr32.exe %systemroot%\system32\RICHTX32.OCX
You should see the message DllRegisterServer in C:\WINDOWS\system32\RICHTX32.OCX succeeded. after running the above command.
