Seems like Miro Desktop App is using: https://desktop.miro.com/platforms/win32/Miro-no-updates.msi in the dynamic versions script.
I think the new URL is: https://desktop.miro.com/platforms/win-nsis/Miro-no-updates.msi
I tested on a machine and it seemed to work.
The version that we are pushing is 0.8 I believe and this one is 0.11 or something like that. Additionally, the version from immybot does not launch properly and gives an error.
Last, I think the two versions are so different we may want to force and uninstall/reinstall for that specific version if possible (but not for the newer versions as they would have to sign in again every update, that’s my thinking i haven’t actually tested.) if I have time later tonight i’ll reinstall a slightly older version and see if the normal upgrade strategy would work. (like from .10 → .11)
