Mercurial problems

Hello,

I have big problem using SourceTree /ST/ with Mercurial. Embedded version is too old and it does not work with latest Mercurial 6.3.1. 

It also does not accept Mercurial installed on System. My System Mercurial works well and it has right path in environment variables but ST does not see it.

Also SourceTreeEnterprice has always disabled button "Update Embedded".

After some restarts ST also stops working with lohal_hg and after reinstall it was OK, but problem System Mercurial exists always.

Its impossible use ST with mercurial anymore.
