Last time I looked at it, it was a no-go: they wanted to do a lot of automated analysis which got hung up on the embedded browser. It’ll be a fair amount of effort for something which is more or less dead.
Thanks for your quick answers :-). If anyone’s interested: I’m currently working on building my own MSI including the plain official syncthing.exe using WiX toolkit to get firewall rules and a windows service created/cleaned upon Install/removal. I could share my draft, but as I’m wrapping it into the windows system Account maybe it wouldn’t fit the culture of an official MSI release… Whoever deploys this via GPO is in the need to setup a GUI password immediately.
