title: When I run the git-gui in git bash on windows 10 I get "line 3: exec: wish: not found"
body: <p>I've been using git and the git gui command on windows for about 2 years with no issues.  Recently, I installed ubuntu on windows 10 and enabled the windows subsystem for linx (wsl) and installed git in the ubuntu bash, thinking I'd run git command from there.  Ever since, git is quite broken when I use the git bash as part of git for windows.</p>
  
  <p>When I run git gui in the git bash prompt in git for windows I get </p>
  
  <pre><code>C:/Program Files/Git/mingw64/libexec/git-core\git-gui: line 3: exec: wish: not found
  </code></pre>
  
  <p>One thing I find really mystifying about the above output is that the slash before git-gui is a '\' backslash while the others are forward slashes, though it's probably irrelevent?</p>
  
  <p>I can still successfully run git gui from the windows context menu (when I right click a folder).</p>
  
  <p>Things I've tried:</p>
  
  <ul>
  <li>uninstalled git from ubuntu</li>
  <li>uninstalled ubuntu</li>
  <li>uninstalled git for windows and reinstalled after restart</li>
  <li>uninstalled git for windows, removed git folder from program files, and reinstalled after restart</li>
  <li>installed wish by installing tk on windows <a href="https://tkdocs.com/tutorial/install.html#installwin" rel="noreferrer">https://tkdocs.com/tutorial/install.html#installwin</a></li>
  <li>reinstalled git to C drive (avoiding the space in "program files" which can cause bugs).</li>
  <li>Added c:\Git\mingw64\bin to my user path variable</li>
  </ul>
  
  <p>activeTCl/bin (which contains the wish.exe) is on my system path.  When I run 'wish --version' in git bash a little empty window pops up, wish seems accessible, whatever it is.  Never needed wish or ActiveTcl to run git commands before, so I'm a bit mystified by that as well!  Anyhelp would be appreciated!  If wish is needed by git for windows why isn't it installed by the git for windows installer?</p>
  
  <p>As requested, Here's the options I used when installing git for windows:</p>
  
  <ul>
  <li>Installed to C:/Git </li>
  <li>Components: ✔️ git Bash Here, ✔️ git Gui Here, ✔️ Associate .git* configuration files with the default text editor, ✔️ Associate .sh files to be run with Bash. </li>
  <li>Use Visual Studio Code as Git's Default editor.</li>
  <li>Path: How would you like to use Git form the command line?  Git from the command line and also from 3rd-party software.</li>
  <li>https transport backend: use the openSSL library</li>
  <li>line endings: checkout windows-style, commit unix-style</li>
  <li>terminal emulator: use MinTTY</li>
  <li>extra options:  ✔️ enable file system caching, ✔️ enable git credential manager, ✔️ enable symbolic links</li>
  <li>did not opt for experimental built-in add -i/-p</li>
  </ul>
