Cannot instantiate Cyclone V Hard Processor System in Platform Designer 18.1

Managed to find workaround by myself:

When working on linux.

It looks like Platform Designer scripts does not handle @ in the installation directory ( $QSYS_ROOTDIR)

Reinstalled somewhere else eg.: /opt/quartus

Comment:

Actually it is mentioned in documentation:

No special characters or symbols, such as !$%@^&*<>,
