1. Close Microsoft Outlook.

2. Go to Start > Run

3. in the open window enter

regsvr32 -u <"full_path_to_Anti-Virus_setup_folder>\mcou.dll".

For example, for the application Kaspersky Internet Security 6.0, installed to the setup folder the path will look the following way: regsvr32 -u "C:\Program Files\Kaspersky Lab\Kaspersky Internet Security 6.0\mcou.dll".

4. Click OK.

5. Open the same window and enter

regsvr32 <"full_path_to_Anti-Virus_setup_folder>\mcou.dll"

Unlike the previous line the “-u” parameter is missing in this line.

6. Click OK.
