1. 下载并安装好Git
2. 打开目录C:\Users\XXXX\AppData\Local\Atlassian\SourceTree，XXXX为你当前的用户目录，创建并修改accounts.json文件如下

   [js]
   [
   {
   "$id": "1",
   "$type": "SourceTree.Api.Host.Identity.Model.IdentityAccount, SourceTree.Api.Host.Identity",
   "Authenticate": true,
   "HostInstance": {
   "$id": "2",
   "$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountInstance, SourceTree.Host.AtlassianAccount",
   "Host": {
   "$id": "3",
   "$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountHost, SourceTree.Host.AtlassianAccount",
   "Id": "atlassian account"
   },
   "BaseUrl": "https://id.atlassian.com/"
   },
   "Credentials": {
   "$id": "4",
   "$type": "SourceTree.Model.BasicAuthCredentials, SourceTree.Api.Account",
   "Username": "",
   "Email": null
   },
   "IsDefault": false
   }
   ]
   [/js]

3. 打开C:\Users\XXXX\AppData\Local\Atlassian\SourceTree.exe_Url_wqdtv3oppzegezgocz22bstjv2dynnpc（该目录可能不一致，找到以SourceTree.exe_Url_开头的即可。）
   接着进入”3.1.3.3158“目录，打开user.config文件，在SourceTree.Properties.Settings代码块内加入如下代码。

   [js]
   <setting name="AgreedToEULA" serializeAs="String">
   <value>True</value>
   </setting>
   <setting name="AgreedToEULAVersion" serializeAs="String">
   <value>20160201</value>
   </setting>

   [/js]

4. 运行SourceTree安装文件，即可

如果弹出让你安装mecurial，选择”我不想使用mecurial”，即可
