My BHO has been registered success but IE don't load it.

Question

Hi,

I follow the microsoft's document building BHO with vs2005 to build my first BHO.

In the first time, it works all right. But when I try to create another project, it didn't work as I want any more.

I checked the registry at "HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Explorer/Browser Helper Objects", My BHO have been registered success. But when I launch the IE, I can't find my HBO in the "Toolbars and Extensions" list.

I search the whole registry and found my BHO GUID appeared in the extension stats element. 

"HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Ext/Stats/AF1CB2E8-5CC2-4EFE-BF39-798ADE03522B"

Any idea?

Oh, BTW, my develop env is win7 + vs2010

Answer 1

This location is for blocked IE addons.

If you are on a 64bit system, make sure you compile your code as 32bit and 64bit versions, as well as register the correct version for both 32bit and 64bit IE.

Thanks for your help.

Maybe I'm not make it clean enough. It works all right in my first  program. 

Can I check the IE log to find out why my BHO is blocked?

Here are screenshot of my dev env and os.

32bit system and 32bit version build

Answer 3

Looks like you are on a 32 bit system. 

I don't think there is an IE log. You can try use CoCreateInstance to create a BHO instance in a test program to see if the BHO is installed correctly.
