If the path is a 64-bit server, try to use 32-bit ie debugging,

It is possible that the generated COM component is 32-bit while the 64-bit ie cannot be identified. On the 64-bit host, the path is (c: \ Program Files (x86) \ Internet Explorer \ iw.e.exe)

Additional: Yes

Debugger type: only local

In some cases, you need to create a New DWORD Value named tabprocgrowth on hkey_localmachine> Software> Microsoft> Internet Explorer> main in the registry, and set the value to 0. However, after deletion, debugging is still available.

Then you can start an IE browser, enable debugging in Vs, set the breakpoint, and then open the corresponding page on IE to debug.
