Mark Thomas resolved DAEMON-445.
--------------------------------
Resolution: Cannot Reproduce
I have tried the registry approach to create an empty environment variable on
all currently supported versions of Windows without success. I am therefore
resolving this issue as cannot reproduce.
I have no objections to this issue being re-opened if steps are provided to
recreate it on a fully patched installation of any currently supported (by
Microsoft) Windows operating system.
