Every published release of the ArcGeek Tools add-in, newest first. The current version is recommended — earlier builds stay available if you need to match a specific environment. Your license key works with any version, and the add-in is free to download with a 16-day trial.
In earlier versions the Antecedent Runoff Condition tables of the Global Curve Number tool were swapped: choosing ARC II (normal) — the default — applied the dry-condition curve numbers, and choosing ARC I applied the normal ones. This is fixed in 1.0.5, so curve numbers produced by this version are higher than before for the same basin. That difference is the correction, not a regression. If you ran an analysis with an earlier version, please run it again on 1.0.5.
Yes. A key is not tied to a version — it works with any release, and the same key covers both the ArcGIS Pro and the ArcMap add-in on the same computer, using a single machine slot.
To match a specific environment or to reproduce the exact output of an earlier analysis. The current release is recommended for everyone else.
No. Installing the add-in replaces the version already present. Close ArcGIS Pro or ArcMap first, run the downloaded file, then reopen the application.
In ArcGIS Pro open Project → Add-In Manager and look for ArcGeek Tools. In ArcMap use Customize → Add-In Manager.
Version 1.0.5 corrects the Antecedent Runoff Condition tables, which were swapped in earlier releases. ARC II (the default) previously applied dry-condition curve numbers. Results from 1.0.5 onward are the correct ones.
