Loosing installs in Section "MainSection" SEC01

I've generated statistics and I find that I'm loosing about 7% of my installations in the

Section "MainSection" SEC01

part of installer. I'm not (yet) able to attribute this loss of users to any particular reason, they just disappear.

Does anyone have any ideas? (I can post the entire section, but it is not terribly complex, basically writing files, setting a few registry entries, etc...)

Losing? What exactly do you mean?

If you are somehow tracking the advance of the installer, the section code itself is not enough. The things that come before it are equally important to understanding.

I'll follow up in a few days, I need to get my client's permission before I can post details on what we are doing and how...
