an older version

Hello!If I have an older version installed on my computer, do I still need to buy a license? I found that my version won't open. Thank you! Sincerely

Dear Kseniia,

If you are using an older version of Fragstats you don't need to purchase a license.
See the license for your version of Fragstats for details.

That being said, the older versions are not supported anymore.
Your problem with starting Fragstats is probably due to your computer's OS/configuration changes. It has nothing to do with the new licensing requirements.

Best regards,
Eduard Ene
