问题：
var obj = marshal.getactiveobject("powerpoint.application")
该代码在管理员模式下运行无法正常获取正在运行的 ppt powerpoint.application 对象，而在非管理员模式下可以正常获取。
针对该问题，微软的msdn官方文档，也没有给予说明。

怀疑 ：和用户有关，没有直接证据。
this code run without problem in release r debug when visual studio isn't started as an admin.
marshal.getactiveobject("outlook.application");however, when i start vs as administrator and run the same line in debug, i get the following error:
system.runtime.interopservices.comexception operation unavailable (exception from hresult: 0x800401e3 (mk_e_unavailable))how can i fix this.
answer :
i would guess that you are running visual studio as administrator (started via run as administrator) while outlook was opened as user, who was logged in as under windows logon. so the visual studio is running under different user than outlook client.
