Okay boys and girls. Installer with sample UI (my EQ2MAP icon replacements) for testing purposes. Zip file format is pretty simple, just archive the mod you want to install with its full file structure intact, but
do not include the UI/CustomUI folder (i.e. include images, images/maps, images/icons, et cetera, but not the overall parent folder.) Name the zip file EQ2Interface.zip. Enjoy.
Oh, and for the love of god, don't try it out on your actual working mod directory without making a backup first. The overwrite and skininfo checks worked correctly in all of my tests, but I really don't want to find a bug on somebody's working directory and destroy who knows what.
Note: the DLL and the ZIP must be in the same folder as the EXE. As always, .Net Framework 1.1 or better required.
Note2: Now that I've ot a beta of the installer out, time to figure out what works well, what could be done better, et cetera. So please, let me hear what you authors want the installer to do, and what you users want the switcher to do.
