i need to upgrade to 3.1 SP5 so i can handle IE9. I log on to my SAP portal and it only has a 32 bit version and i have my isntall on 64 bit windows. My first question is where is the 64 bit version? Also what if i want to go straight to 4.0? Can i perform an inplace upgrade? Can someone send me the link to the upgrade documetation to 4.0? Thanks.
