one way install

[lazurk]

Hello, this is my first post

1. Is there way to make instalation one way?
(I mean without uninstall file, totaly clean.. something like sfx extractor but in nsis design)
2. Need help with thing, when run uninstall, need to backup files which were changed by the instalation (mpq file - game modification) - also extract old backuped ones when uninstalling my changed.

thanks for advance!

yes. this is default.
nsis does ONLY the things you tell it in your script to do.
if you do not explicitly code registry actions, it won't do any.
if you just code file extraction things, it will behave like a SFX.

you may also want to try the NSIS Self Extractor Kit:

2.is a bit more difficult....
