SnapGene is built for 64-bit Windows for Intel.
We do not yet support running SnapGene on Windows for ARM. However, in preliminary testing, SnapGene does install and run on the latest Windows for ARM that includes Microsoft's Prism Emulation Engine.
If you do try SnapGene on an ARM-based Windows machine then let us know how it goes for you! You can contact our Support team with your feedback via our support form – https://support.snapgene.com/hc/en-us/requests/new?
