Cannot deploy with custom meteor installation on Windows

I have a custom installation of Meteor on Windows

because the Windows machine is controlled by IT and has limited disk quota for /users

Therefore I unzipped the code given by avital in C:\Work\Software despite the instructions saying it should be unzipped in %LocalAppData%\.meteor because %LocalAppData% is obviously in /users

Everything works fine except the deployment to which I rarely need so I only noticed now (because I was hunting a bug and wanted to put a sample to reproduce online)

The output of meteor deploy is clearly looking for executable son the wrong place

C:\Work\Software\chart_resize>meteor deploy
Deploying to

C:\tools doesn’t exist and I can’t find it around %LocalAppData% so it might not have been created at all.

Any suggestion ?
