If the installer gives a user the option to not to install Gator and TopText then Limeware should not crash when a user installs this configuration. From a business perspective, if spy-ware is required to support your development model, then don't give people the option not to install it. You just succeed in frustrating everyone who innocently chooses that option. And judging from the posts - there is no hotter issue for you to resolve. I recommend that you put a link on your homepage to a page that explains these limitations immediately.
