Hello Tom
The plugin is not disabled, it is noted as inactive and I can do nothing on this via outllok menus.
And in the registry, the value you indicate is 3 also
Regarding the execution of the command "regsvr32 asoutext.dll", I get an error message (attached) that says:
"the asoutext.dll module has been loaded, but the call to DllRegisterServer has failed with error code 0x80070005
For more information on this problem, make a search in line with the corresponding error code"
WBR.
Patrice.
