>>>One thing you can do is wrap your entire application in a CheckEnvironment() function, which checks that everything it needs is available before the "guts" of the program start. This can be added to your existing code, or implemented as a "launcher" program. As a side note to this, you could code defensively: just because, in a regular installation, a file is *supposed* to be in a given location and accessible with certain privileges, doesn't mean it always *will* be.
>>>
>>>However, in the general case the installation or privileges can be so screwed up that nothing will load e.g. bad or missing runtimes. If your error-reporting code, no matter how defensively written, won't load, then you're stuck. One way to approach that is to make available a troubleshooting web page and/or wiki.
