4.10. Managing Multiple Versions and Copies of Intel FPGA Software

You can install multiple copies of the same version of software on the same computer.
  • To specify which version you want to open by default, setting the QUARTUS_ROOTDIR_OVERRIDE environment variable.
  • To preserve project compilation databases from an earlier version of the software before installing a newer version, open the design in the earlier version of the software and export a version-compatible database for the design.
