Component MSCOMCTL.OCX not correctly registered

MSCOMCTL.OCX error dialog


After I installed MP3Gain on Windows 8 and executed it, it threw this error:

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


This error is caused because either the file MSCOMCTL.OCX is missing or it is not registered with the registry. To fix it, try the following:

  1. Find a copy of this file. You might find this file somewhere among your Windows application directories or can be found online. Place the file in a directory which will not be tampered with.
  2. Open a command prompt with Administrator privileges.
  3. Register the file by using the regsvr32 command: regsvr32 C:\path\to\MSCOMCTL.OCX

After the registration is successful, run the application again and it should execute without throwing this error.

Tried with: Windows 8 x64 and MP3Gain 1.2.5

  2. The one of the main and important problem occurs in computers that is MSCOMCTL.OCX sometimes certain microsoft libraries can become unregistered in installation or download any new software in the computer on that time this problem will start occurrence
