是否可以选择在Windows中启动进程时使用的清单？(Is it possible to choose a manifest to use when starting a process in windows?)

 我试图提供一个COM对象，可以用来替换我无法控制的可执行文件中的对象。 我已经使用所有相同的接口创建了这个COM对象的实现。 我希望能够偶尔使用这个替换，所以我不希望它的注册替换原始对象。 
 
 我可以通过修改可执行文件的清单来查看com对象而不是通过注册表查找原始文件，从而使用reg-free COM来获取可执行文件以加载我的COM对象而不是原始对象。 
 
 到现在为止还挺好。 但这样做需要修改可执行文件中的清单文件。 我不希望此更改是永久性的，并且由于可执行文件通常安装在“程序文件”中，因此还需要管理员权限才能更改此文件。 
 
 理想情况下，我希望保持原始可执行文件不变。 然后在需要时，我创建的单独的启动程序将使用重定向到我的com对象而不是可执行文件中的原始清单文件的清单来加载所请求的可执行文件。 
 
 这样的事情可能吗？ 或者也许是一种更好的方式来做我想做的事情？ 
 
 注意：我可能无法制作可执行文件的副本，并且在我具有写入权限的位置更改了清单，因为我事先并不知道此可执行文件的所有依赖项将是什么（它可能需要来自相同的目录，或子目录中的数据文件）。 我可以将修改后的可执行文件的工作目录设置为原始可执行文件的目录，但如果可执行文件根据其文件位置执行任何操作，则会中断。 

I am trying to provide a COM object that can be used as a replacement for an object in an executable that I do not have control of. I have created an implementation of this COM object with all the same interfaces. I want to be able to use this replacement only occasionally so I do not want its registration to replace the original object.
 
I can get the executable to load my COM object instead of the original using reg-free COM by modifying the manifest of the executable to look in my dll to find the com object instead of finding to original through the registry.
 
So far so good. But doing this requires modifying the manifest file in the executable. I do not want this change to be permanent, and since the executable is usually installed in "program files" it would also require administrator privileges to change this file.
 
Ideally what I would like is to leave the original executable unchanged. Then when needed a separate launcher program I created would load the requested executable using the manifest that redirects to my com object instead of the original manifest file in the executable.
 
Is something like this possible? Or maybe a better way of doing what I am trying to do?
 
Note: I probably can't make a duplicate copy of the executable with the manifest changed in a location I have write access to because I do not know ahead of time what all the dependencies of this executable will be (it may need dlls from the same directory, or data files from a sub-directory). I could set the working directory of the modified executable to be the directory of the original executable but if the executable does anything based off of its file location it would break.
