Help - can't install "Specified cast is not valid"

Tue, 06/14/2011 - 07:28 — spenol

Hi,

I've tried installing the demo version of Organiser, but after the Outlook Add-in installer opens, I get the error "Specified cast is not valid", followed by the following error. Any ideas? I'm running Outlook 2007 on Windows 7.

Thanks,

Oliver.

Change UAC to default

Thanks for the note Oliver...

Per our e-mail thread and to share with other folks that may have this issue.

Changing the UAC setting to default and rebooting seemed to work.

This was for Windows 7.

Thx
Chris
