Running 32 bit oracle on 64 bit windows
My oracle client version is 10.2.0.1 32 bit for windows. My OS is windows 7 in 64 bit. The client installation run fine. I can connect to sqlplus ok. But I couldn't connect to any applications such as access to pull out data from oracle. I searched online and found this note: 334528.1 on this site. According to the note, I downloaded the patch 4923787. But when I try to install the patch, I got the following error: opatch failed with error code=255.
java.lang.NullPointerException
