命令无效：SysRestore :: StartRestorePoint在NSIS中使用SysRestore插件

Question

我想在我的NSIS 2.46安装程序中创建系统还原点。我搜索了一下，发现SysRestore插件是最好的选择。

我从http://nsis.sourceforge.net/SysRestore_plug-in下载了SysRestore.zip，解压缩并将其复制到NSIS的安装文件夹中。但即使是发布的示例（\Examples\SysRestore\example.nsi）也无法正确编译。

日志如下所示：

在我的知识，一个NSIS插件应该提供一个.nsh文件被列入.nsi脚本。包含头将提供有关功能的定义，如SysRestore::StartRestorePoint。所以编译器不会抱怨它。

但是我没有在SysRestore的文件夹中找到.nsh。这个插件有什么问题？或者我的使用中缺少某些内容？

谢谢！

Answer 1

您不能仅从解压缩的存档中复制文件夹，因为它使用NSIS 3.x文件结构进行插件。尽管如此，复制文档和示例的文件夹效果并不理想。

使用NSIS 2.x时，请确保将Plugins\x68-ansi\SysRestore.dll复制到%PROGRAMFILES%\NSIS\Plugins。

Answer 2

看这个编译时消息，下面几行：

Processing plugin dlls: "C:\Program Files (x86)\NSIS\Plugins\*.dll" 

SysRestore :: StartRestorePoint不会出现在加载的插件列表。您是否将SysRestore.dll复制到插件文件夹？如果您只是将其提取到其他文件夹，则需要使用!addplugindir并包含该文件夹。
