Sourcetree Git Flow not Supported

[Jana Kemmer]

Hello, 

We have been using Git-flow for a while. On some projects it seems to work fine, But on most projects I can't use Git-flow.

Every time I press the Git-flow Button I get the following Error Message:

Git-flow not supported.
You'll need to upgrade to Git 2.6.4 or later. 
We recommend upgrading to Git 2.24.1.2

When I use Git-flow via command line everything works as expected.

I am using Embedded Git with Version 2.24.1 

My Sourcetree Version is 3.3.8.3848

I tried everything that I've found in here so far, but nothing worked.

After selecting checkbox "Tools/Options/Git/Git Version/Disable LibGit2 integration" the error message does not appear any more for "Git-flow/Start New Hotfix" action in my case.

(Win/System Git version 2.16.1/Sourcetree 3.3.9.3870)
