Hi Hendry,

I have a suggestion for you.

It has been found that in Vista, a new security mechanism was introduced called UAC (User Account Control).

The problem is to register DI and UI - a COM object, therefore user must

do the following:

1. Turn off UAC (disable UAC) before installing the client so the

registration of both the UI and DI will work.

2. Set the "Run as Administrator" property of regsvr32.exe.

Hope this helps,
