A prior .exe(NSIS) install leaves Tailscale on disk but not on PATH; the MSI then fails with error 1603 trying to install over it. Now detect the existing binary at C:\Program Files\Tailscale\tailscale.exe and skip installation, and treat a nonzero msiexec exit as success when the binary is already present.
