Selected both "upgrade" and "custom install", and the setup program loads stage2.img and HANGS while "verifying packages" ("exception occurred"; I then have a choice to "debug" or "ok". "ok" then shuts down and tells me that I may reboot my machine; I don't know what to do with "debug"). Have "rpm -K"'d my RedHat/RPMS directory and all is well there; have redownloaded and rewritten boot.img using both "dd" in Redhat 6.0 and "rawrite.exe" in msdos and had the same problem.
Please submit the details of the exception that you are getting. Especially the end of the traceback as that shows where the problem actually occurred as well as what the problem is.
Closing bug due to non-activity.
