I discovered today when trying to install a Keyman keyboard in 16.0.139 from a remote desktop accessing a shared folder on the network, it went through the motions of installing, but it didn’t actually get installed until I copied the kmp file to the active machine. It would be nice if it would install through a Windows network drive as well.
Yeah, we’re aware of this; see for example #7207 which mitigates the problem by at least not crashing! The basic problem is that the elevated process which does the actual file copy into %ProgramData% doesn’t have access to the network share, even when the logged-in user does.
A mitigation which we have considered is copying the file in the original process to a temp folder on the local drive, and then giving that temp path to the elevated process. This will resolve the problem for the majority of situations, at the cost of a marginally slower keyboard install.
We don’t have an issue open for this at present, so please do feel free to open one if you think this is worth addressing. 
@Ken_Zook Please reply to this topic if you need further assistance, otherwise it’ll be closed in three weeks.
Removing the close timer, as there is an open issue for this on GitHub.
