installed

I think the interface is fine, i mean how long do most people spend staring at their file archiver?

#3.1 noxcuse on 17 Apr 2007 - 10:21

Exactly. Most of the case, right-click, extract ... / extract here.

Yep, I still use 7-zip to make all my silent installers for stand-alone, portable deployments of apps on systems.

I like this app, but it annoys me more than an estate agent from Birmingham talking loudly on his mobile phone with his mouth full of food on a long train journey that i have to restart windows to complete its installation.

I've never had to restart once in my life from this installation. I install it, I use the portable version, I uninstall it, reinstall newer versions afterwards, etc. and have never once in my life had to restart a machine because of the install procedure.
