Unable to run apps from a FAT drive

[phprogrammer]

I'm having trouble executing the apps from a FAT drive. Is there a way to use them even though FAT does not support Unix permissions?

Thanks!

Recently the hardware abstaction layer (HAL) was changed so that FAT volumes are mounted with the "showexec" mount option. This is not specific to AppImages, it effectively prevents any executable from being executed on FAT partitions (even shell scripts). You can find out if you are affected by this by typing "mount" - if you see "showexec" in the output, then that is the likely reason.

There is a hack you can use to revert the behavior back to normal:
