During installation of .deb package, which we have made before, cannot start hello-node service, it tells that service is not found.

Failed to start hello-node.service:
    Unit hello-node.service failed to load: 
         No such file or directory.

If Windows Updates have installed, but the computer has not been rebooted, the installer may fail.

If any MSI is currently in progress, the installer will definitely fail when attempting to install NodeJS via MSI.

Perhaps the exe version of NodeJS could be installed.

In any case, it should test for pending installs / windows updates / reboots and advise the user to reboot and try again if the install doesn't work as expected.

I always got this error of "Compiler cannot find the specified path", when its trying to compress my node_modules.

Is it a matter of too long path again ? Sometimes with node_modules on WIndows, there are always problems with longer path ...

Ideally this should check for NodeJS.

If it is older, but not too old (>= 0.6.0), it should update NodeJS.

If it is newer, but not too new (< 2.0.0), it should not install NodeJS.

If it is too new or too old it should fail with an error message.
