I have been running successfully making PLA items using Repetier 0.84 and slic3r 0.9.8 on my laptop under Microsoft XP Pro. I want to try ABS filament and the slicer configuration file K8200-ABS-Standard-New requires Repetier 0.90 and Slic3r 0.9.10b. I have downloaded both of these, and also the PLA-New file but when I start to run Slic3r it prints an error message “executable is not a valid Win32 application”. Is this a problem with the XP operating system, or have I installed it incorrectly?
That sounds more like you are running a 64-bit application on a 32-bit computer.
