- Un-install all previously installed modem files.
- Restart the computer.
- Go to Start Menu
- Run ‘regedit’
- Open this key:
- In this key, find the “Installer32” string.
- If the Microsoft Registration Key is missing, the key has to be added manually.
- Create a “string” value named “Installer32”, and set it to “mdminst.dll,ClassInstall32”
- Save the ‘regedit’.
