If you try to install Visual Studio 6.0 on Windows XP SP2 system, the setup prompts to update MS JVM and restarts. Sometimes even after the restart it prompts to install MS JVM again, and gets into this infinite loop.
A workaround is to copy the CD contents to a folder, open SETUPWIZ.INI, and delete the line VmPath=ie4\msjavx86.exe . Setup will not prompt for MS JVM install anymore.
If Setup.exe crashes on XP SP2 system, set the compatibility mode on SETUP.EXE to 'Windows NT 4.0' or 'Windows 2000'.
