Hey there.

My organization is having problems updating to the newest Mercurial version (1.10.6) from the previous version 1.9.7.
We get the following error: Could not determine Mercurial Version. This is at the "Hg Executable Path" section in the installer.

All help is appreciated, thanks! :)

    Was missing the Mercurial installation altogether in the newest update 1.10.6, as it wasn't a requirement in 1.9.7.
    After installation it went smoothly.

    Hello, Jesper!

    Do you have Mercurial installed on the server?

    Hey Anton.

    Sadly my problem isn’t resolved. You are right about Mercurial missing, but after install of Mercurial standalone (Mercurial 3.9.1 MSI installer - x64 Windows - requires admin rights, from: https://www.mercurial-scm.org/downloads )
    The install fails at the end and is reverting all of the install steps. The log points to mercurial as the issue when I look at it with my eyes.
    I found somewhere in the install guide that any mercurial version 3.x.x+ should be sufficient, so I really hope that you can help me. Thanks in advance :)

    Saw these in the install log:
    Property(C): INSTALLLEVEL = 1
    Property(C): WIXUI_HGEXECUTABLEPATH_ERROR_REASON = Command 'hg version' returned 'Mercurial Distributed SCM (version 3.9.1)

    Here's the log. Some things have been redacted.

    A quick question before I go spelunking into the logs: can you double-check
    that there are no |, \ or / symbols in SQL Server login or password?

    Yes. I can confirm that there's no such characters in either login or password.

    Hello Anton.

    Do you have any news regarding possible errors in the log or steps i can take to get updated with the newest HGLabs version?

    Thank you for you time.

    MSI is a mess. May I ask you to completely remove all traces of HgLab (that
    is, delete everything from under C:\Program Files (x86)\HgLab HQ and from
    IIS) and start the install over? Or this is unacceptable in your situation?
