Can I install OpenRoads 2021 release 1 side-by-side 2021 release 2?

Can I install OpenRoads 2021 release 1 side-by-side 2021 release 2?

if this is not doable, can I use release 2 to open dgn files created with release 1, without upgrading the dgn file so it is still accessible to team mates who still use release 1?

  • You cannot install two release versions within the same year. It will upgrade the earlier release. But you can install multiple year versions.

    Different DGN files created and modified by different Releases within the same "year" designation are interchangeable within that same year version. Crossing a Year number requires a schema change. In other words, you would need to use the Civil File Manager to downgrade a file to an earlier schema. And if you open a file with a newer year (i.e schema) the software will warn you with an offer to open it read only. Unless a specific variable has been defined to suppress that message.
