It should be compatible. But if you have Windows 10, why would you choose 0.9.7? Sigil 0.9.10 is the last official release to supply a pre-built 32-bit Windows version. And there's even a 32-bit 0.9.13 Legacy version of Sigil in my repository that should work fine:

I'll check to see why an older 32-bit version of Sigil might not work on Windows 10 (32- or 64-bit), because there's no reason I can think of that it shouldn't.
