How to Install a COM using ClickOnce

Question

I have installed my windows application that uses TeeChart ActiveX (a COM Component for charting) using ClickOnce.

If I register manually TeeChart using regsvr32 teechart8.ocx, my application works fine. But I want and I need to install the application using ClickOnce.

How can I do that?

ClickOnce can only copy files. So you have these options:

Use Reg-Free COM as Jeff Hall suggests. This is probably the best option if you can do it.
Run regsvr32 manually when your .exe file first loads (before it tries to access the COM objects)
Create a custom clickonce prerequisite package which installs the COM objects

The link is broken after many years of maintenance. If you could correct it that would be awesome. Still very useful. – kennyzx Jan 29 '19 at 13:24
