Due to project requirements, you need to access domino emails, and there are still a lot of information on the Internet. Find a piece of code and write a test program as you may have done!
An error is reported when calling the Domino class:
[Python]
Failed to retrieve components whose CLSID is {29131539-2EED-1069-BF5D-00DD011186B7} in the COM class factory because of the following error: 80040154.

I don't know why. Generally, the following DLl is reregistered on the Internet.
[Python]
Regsvr32 "C: \ Program Files (x86) \ IBM \ Lotus \ Notes \ nlsxbe. dll"

After n times of execution, the registration is successful, and the registration is canceled. the problem persists!
However, I installed Lotus Notes on my machine and added Com references. Why can't I call Lotus Notes? Suddenly, my system is Windows 7 64-bit, And the lotus note client program is all 32-bit. Is that the reason? Open the project properties, change the target platform from Any Cpu to X86, and run again. OK!
