Atmel AVR IDE/assembler won't run (Windows 8)

I'm trying to write some code for my AVR in assembly, but I cannot get either the Atmel studio 6.0 (with or without sp1) or AVR32 studio 2.6 to run. Studio 6.0 with the service pack states that it will work on windows 8 but consistently gives the error message "The application was unable to start correctly (0xc000007b)". AVR32 generates a Java error. This is consistent across all compatability settings and running as administrator.

This is on a pretty much clean install of windows 8 pro x64, with all updates and the latest release of both 32 and 64 bit Java. All other software has installed and run without issues, including the equivalent software for microchips microcontrollers.

I would appreciate any suggestions as to how to get this software to run, or any alternatives that may work.

Thanks in advance for any help.
