Filemaker Pro does not run on ARM CPU, so no Windows 8 RT.
But Filemaker Pro should work fine on normal Windows 8 on x86 CPUs.
windows 8 RT does not allow any executable files to run. It requires a app like FM Go. I hope, but am not holding my breath, that FMI put out a version for W8 RT. FM has a history of being cross platform so it would make sense.
In 3 months Microsoft will be releasing a Surface tablet with the full version of win 8. FMP will be able to run on that.
Thanks Jogn. Very helpful.
