From last many months, I was using the MS Office 2003 for my desktop computer. Now I decided to install the Office 2010. My computer is running the Windows Vista x64 business edition. I have installed the "Office Home and Business 2010" edition in UPGRADE mode. I was in administrator account and all are running fine it. I was able to open the Outlook mail file without any problem.
The problem starts when I logged in with the standard user account. I use that account for dealing with my emails. When I tried to open the outlook utility then it refuses to launch that. All other things like Excel, Word, PowerPoint and OneNote are running without any issue. Can you tell me that what can be the problem with this and how can I solve that?
