Thank you Srikishan! I was able to install the SAP GUI that was installed on the 32-bit system; however, I am having trouble logging in. In my original 32-bit installation, I would log in with username: BCUSER and use the password "abcd1234". On this 64-bit installation, it will not let me log in with those entries and I get a "Name and password is incorrect (repeat logon)" error.
I even tried logging in with the (2) preinstalled users of DDIC (pw: 19920706) and SAP* (pw: 06071992) from the start.html page from my installation folder but had no success. Do you know why I am getting the logon error?
