Sourcetree Enterpeise cannot find perl.exe

[e_blaauw]

Hi,

Using SourceTree Enterprise (version 3.3.6 as 3.3.8 doesn't start at all) on Windows Server 2012, I cannot connect to my Azure git repository. I can authenticate with my account, but when I try to clone a repository, it says it is not possible ("This is not a valid source path / URL"). I get the error below. It seems perl.exe is missing? How can I solve this?

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://actiz.visualstudio.com/<REPO>
Output:
Error: fatal: Authentication failed for 'https://actiz.visualstudio.com/<REPO>'

Command: perl.exe "C:\Program Files (x86)\Atlassian\Sourcetree\tools\svn.pl" info https://actiz.visualstudio.com/<REPO>
Output:
Error: System.ComponentModel.Win32Exception: The system cannot find the file specified
