Hello all,
I am new to bat mud, and took it as a challenge to get the client working on my XP64 machine. After a few hours I got something that will work.
First do the following.
Start-->Run-->regsvr32 urlmon.dll
Start-->Run-->regsvr32 Shdocvw.dll
Start-->Run-->regsvr32 Msjava.dll
Start-->Run-->regsvr32 Actxprxy.dll
Start-->Run-->regsvr32 Oleaut32.dll
Start-->Run-->regsvr32 Mshtml.dll
Start-->Run-->regsvr32 Browseui.dll
Start-->Run-->regsvr32 Shell32.dll
This lets the DLL's that Java uses act as a 32 bit DLL.
Then download the Java 5.0 Runtime Environment. When prompted choose custom install. Then change the directory to C:/program files/Java/Java. (You have to delete tie (x86) from the program files, and you cannot have any spaces, dashes, dots, or underscores in the final folder.) After it installs run and enjoy :)
