In-app updates
Lumo checks for a new version once per launch and offers to install it from Settings.

Windows will say “Unknown publisher”
Lumo’s installer is signed, but with a self-signed certificate rather than one from a commercial CA. Until Windows trusts that certificate, every download shows the sameUnknown publisher warning an unsigned file would. Signing does not build reputation, so the certificate has to be installed for the warning to change — it does not change on its own.
Installing it tells Windows to trust CN=Lumo, O=kiwilabs, after which Lumo shows as a named publisher. This is the usual trade-off for a self-signed app: trust is granted by you, not by a third party.
- 1Download lumo-signing.cer and check the publisher reads CN=Lumo, O=kiwilabs. Only continue if it does.
- 2Open a terminal and run the two commands below. The first makes the certificate a trusted root so the chain completes; the second marks Lumo as a trusted publisher.
certutil -addstore -f Root %USERPROFILE%\Downloads\lumo-signing.cer
certutil -addstore -f TrustedPublisher %USERPROFILE%\Downloads\lumo-signing.cerTo remove it later, run the same two commands with-del instead of-addstore. Fingerprint34AFFCB15BD60F4D9560A564CF6C821ECD45C373. Only install a certificate you downloaded from this page over HTTPS.
