I zip all the files with the config.txt and 7zs.sfx files added. But when I run the new EXE file, I get the error: Program Too Big To Fit In Memory.

Wtf?

extract that to say C:\7zmaker or something

put your installation files into one 7z file

the config.txt file has the line "Installer.exe", you can edit this to installer.bat or whatever if you use a bat file to install with

place your 7z file in the 7zmaker directory, then double click the bat file in the 7zmaker folder, this will make the exe for you and call it done.exe, this is now ready to have its icon change via reshack, and you can manually rename the exe
