SourceTree failed to start

Keith Olson

Please help!

On Windows 10, SourceTree wasn't opening anymore, so I removed the software and deleted the Atlassian folder in my users/AppData/Local folder, then downloaded and reinstalled SourceTree v.2.3.1.0. Same problem.

I found the sourcetree.log file, and this is what it contains:

ERROR [2017-09-19 09:28:53,181] [1] [SourceTree.App] [.ctor] - finish EnsureSquirrelExecutionStubIsCopied

Hello! This is a known issue. Please navigate to the config file location (C:\Users\{USERNAME}\AppData\Local\Atlassian\SourceTree.exe_{RANDOM_GUID}\2.3.1.0\user.config) and find the following line:

<setting name="AutomaticallyCleanUpDictionaryFiles" serializeAs="String"> 
     <value>True</value> 
</setting>

Make sure that value is set to True

Hi everyone! As an update, we've started the progressive rollout of Sourcetree v2.3.5.0 which includes a fix for this issue. You should be prompted to upgrade at some point over the next 14 days or, alternatively, you can download it directly from https://downloads.atlassian.com/software/sourcetree/windows/ga/SourceTreeSetup-2.3.5.0.exe

Cheers

Ana

I had to add this setting, as it was not present probably due to reinstalling to try to fix the problem. But adding the setting fixes it. The installer was not even running without this setting.

Keith Olson

That did it! I'm glad it was a simple as that.

Thanks much!

MarconiM

Thank god! That was it. Worked instantly after adding the setting and running sourcetree again.

// SourceTree.Notifications.NotificationsManager
private static void SetOwner(NotificationDialogWindow notificationWindow)
{
    Window currentWindow = WindowsOSHelper.GetCurrentWindow();
    Window window = (currentWindow == notificationWindow) ? null : currentWindow;
    if (window != null && window.IsVisible)
    {
        notificationWindow.Owner = window;
        return;
    }
    NotificationsManager.Logger.Error(string.Format("Unable to set owner as parent {0} is not visible", window.Name)); // <- Problem's here. If windows == null. It's not going to work.
}

Same bug for me. No workaround works.

Hi @Nicolas Frelat,

If you do have the same call stack in you log file, here's the other way to fix the issue:

1. Open RegEdit. Navigate to:

2. Computer\HKEY_CURRENT_USER\Software\Microsoft\Spelling\Dictionaries

3. Double click the "_Global_"

4. Check each file and see if they exists.

5. Remove the one that's not there.

6. Hit OK.

7. Start your SourceTree.

There's another solution provided by @Mike Corsaro might also be working. However:

1. You might be scared, as I was, by both the popup message or the setting name "Remove the dictionary files" or "Cleanup dictionary files". In fact, it's not going to remove any file but the path of the non-existing file in the registry if you read the source code.

2. You might find that there is no such "AutomaticallyCleanUpDictionaryFiles" in the user.config file on your local machine. And you entered the panic mode because the file is huge and you don't know where would be the right spot to put it in as I did.

Cheers,

Frank

P.S.:

Not sure why they think the missing files will causing the slowness. Maybe it's about the network issue. However, I don't really like the way it is now which confuses users a lot. It should:

1. Measure the time of loading the dictionary files and ask users if they like to not loading these files if it's too slow. Trying to load a missing file on local machine should not be taking too long, especially compared with the time asking user to read the popup and think about why I have to do that. Or,

2. Lazy loading the files asynchronously. It should not be affecting the core feature even if some of the files do not finished loading on time. Or,

3. At least fix the message to not scare the user but tell the truth. It's not cleaning up the files. The files are not corrupted. It's just prevent check and loading the non-existing files only.

Hi,

The registry edition tip did the job! After the change, I had some more glitches but now it works.

Thank you.

Dan Haywood

None of the above worked for me, but the solution on this thread https://community.atlassian.com/t5/Sourcetree-questions/SourceTree-will-no-longer-start/qaq-p/642054#U648488 did work.

coder_trader

It works for me, I added to the file

<setting name="AutomaticallyCleanUpDictionaryFiles" serializeAs="String"> 
     <value>True</value> 
</setting>

Markus Weser

Thanks! Adding this setting solved for me (Win 10 16299.15, SourceTree 2.3.1.0)!

Philippe RIVAT

Merci beaucoup.
Arrêtez de pleurer alors que vous ne payez même pas le logiciel !!!

OMG! Can you just fix this problem in new version?

For searching solution I'm lost all settings...

Can you explain why SourceTree installs in the user appdata folder rather than program files folder like most windows apps? I find this very strange.

Andy Luff

None of the above solutions worked for me. Tried a clean install of 2.3.5 after deleting all %localappdata%. Same error... [ERROR [2017-11-08 15:53:23,111] [1] [SourceTree.App] [.ctor] - finish EnsureSquirrelExecutionStubIsCopied]

Wasted too many hours on this, now moving to alternative product.

Ian Daintith

Amazing. I lost 2 hours today with this.

colinrobertbrooks

I'm in the same doom loop. What did you switch to?

hitokun-s

I'm in the same situation. I tried many products, but nothing was better than Sourcetree. I hope SourceTree dev team investigate this issue seriously...
