I’m using currently Windows 7 with Office 2010. Office 2010 looks good so we have a ribbon menu in all products (Visio, Outlook). I’m working most of my time with Dynamics CRM I tried to install CRM Outlook Client but without success. As usual there is workaround for it. Go to registry path
HKEY Current User\SOFTWARE\Microsoft\MSCRMClient
Create DWord (32 bit) value
Installator will show error but you will be able to continue.
Microsoft Dynamics CRM 4.0 support only 32-bit Outlook Client.
