I am trying to clone a mercurial repo from bitbucket and am getting the attached message.

I can't update beyond this version because the .net version that is used is not "approved" for the version of windows 10 that the company uses.

I have tried updating my system mercurial to 4.7.1 and set SourceTree to use that as well.

Command: perl.exe C:\Users\iaoswa\AppData\Local\SourceTree\app-2.4.8\tools\svn.pl info // URL
Output:
Error: System.ComponentModel.Win32Exception: The system cannot find the file specified

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false ls-remote 
Output:
Error: remote: Mercurial (hg) is required to use this repository.
remote:
remote: https://confluence.atlassian.com/x/vLRCMw
fatal: unable to access /* URL */: The requested URL returned error: 405

Command: hg identify extensions.hgext.hgsubversion=! 
Output:
Error: *** failed to import extension hgext.hgflow from ..\SourceTree\app-2.4.8\extras\hgext\hgflow\hgflow.py: 'module' object has no attribute 'command'
