Need to take somebody's else BHO project

I need to take up somebody's project who left the team.

The project relates to IE extension development.

The project I was given compiled was without .vdproj

The project is known to compile fine and register itself with internet explorer as extension.

However the files given to me, although they compile fine, are not able to register itself with internet explorer as an extension.

What needs to be done in this case?

there's probably your answer, right there with the comments. setting _value to 1 prevents the BHO to be loaded, and it happens right below there.

i was able to find out the problem, and i was able to register it manually using regsvr32.
