可能出现的问题和解决方案

Windows限制可用的覆盖图标的数量，参考Kris Erickson的回答。 TortoiseSVN设置不当，参考Ralph Cowling的回答。 从早期版本(1.6.10之前)更新的已知错误，请参阅这里。 TortoiseSVN并不是为所有用户安装的，尝试像下面这样用cmd安装，如果下面三个解决方案都不工作，我相信这个方法会挽救你的生命。

如果有人需要64位Windows 7的注册表项，这里有。对我有好处的是删除不经常使用的项目的覆盖:Drop Box，谷歌Drive，微软产品，只保留乌龟的覆盖。这些都是覆盖-没有被删除。

**注意**玩弄注册表会使您的系统不稳定。一定要备份您的注册表。关于备份注册表或注册表设置的各种方法，请参阅谷歌搜索。

记住，这些都是64位的Windows，你应该备份你的注册表

在Windows 7 x64上升级到1.6.8后，我也失去了我的覆盖。我只安装了x64版本，没有安装32位版本。为了解决这个问题，我使用原始安装程序进行了修复并重新启动。覆盖之后正常显示。

它们在这里陈列得很好。你是否同时使用64位版本的Windows 7和32位版本的TortoiseSVN?如果是，那么它们将只显示在32位资源管理器中(或32位应用程序的cfd中)。不过，您可以同时安装32位和64位版本。

我的偶像也消失了。注册表修复对我也不起作用。

我是这样把它们找回来的:

安装最新版本的tortoiseoverlay 重启资源管理器

为了完成Johannes的回答，你可以检查这个线程，其中提到了另一个原因(第一个原因是安装32位客户端而不是64位客户端)(强调我的):

只有最新版本的TSVN和TCVS能够共享覆盖图标，并且由于资源管理器有14个覆盖图像和无关的覆盖图标的限制 只是不出现你可能有太多… 如果它的覆盖图标显示，你必须实际使用 32位的Windows资源管理器，这当然意味着你也必须这样做 安装32位版本的TSVN。

在安装TortoiseVCS时可能会出现这个问题，因为:

Looking at what got installed in the filesystem and the registry, it looks like they tried to do what I do with my Shell extensions - install both 64 and 32 -bit versions, so that nobody says "I don't see my overlays/menus"! ;) Unfortunately, it looks like the registry entries for 32-bit got hosed, so the 32-bit extension DLL, even though present, does not have the correct registry entries. If in doubt I suggest to deinstall TCVS and TSVN. Then install TSVN. Maybe after installation reboot twice, not only once. And if they still don't show up go to software control panel and choose to repair the installation. That did the trick for me with when upgrading from the previous to the current version. You should probably install the TortoiseXYZ variant you plan to use mainly first, to improve its chances to fall into one of those limited number of overlay icons slots before the TortoiseXYZ variant you use less. Always keep these limited number of overlay icon slots in mind when trying to analyze malfunctions.
