I installed MS office Professional plus 2010 64bit after removing the MS office pro as it didn't have the 64bit setup.exe.. SINCE I have done that I get an error "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client" I have deleted the MSMAPI32 and made sure it was set as the default program. Any more ideas?
