quartus libprotobuf.so.14 requirement

Hi Richard

I installed it on RHEL 9.

The problem came down to the quartus installer not setting permissions correctly.

All the libraries were there (in quartus flatpak library folders).

It seems to set a lot of the permissions for libraries etc to user only, in this case the owner was root as they performed the installation.

However all things things that need to be executed including libraries should be set with 555 permissions so other users can read and execute them.

Config/data files etc files should be set with 644 permissions.
