A silent install of Alcohol 120% can be done with setup.msi /qb, but as already pointed out this will not install mount & un-mount explorer extensions. I have little use for Alcohol 120% apart from this function.

I have tried an install kit with InstallRite but Alcohol 120% will not work, complains about missing cdrom driver and must be re installed.

Does anybody know of a way to get the explorer extensions to work?

To get the explorer extensions to work, you have to use setup.exe instead of setup.msi:

setup.exe /qn Reboot=Suppress

(Latest version 1.4.8.1222 forces a restart now, hence the Reboot=Suppress)

OK, sorry to be a pain here guys, but I have got this to work.
Seems I was entering my registration details before install, if I install first then register everything works fine.

Just saw your reply as I was posting Aaron, thanks
But like I said I managed to get it to work so I think I will leave it at that, thanks for the reply.

u can make an msi installer if u want..
I made one for myself for the latest alcohol. the registry key is integrated.. no reboots no cmd lines...

XtremeMAC How can you make that MSI file??? if I may ask...

Get an msi editor like wise or MaSaI. I personally prefer AdminStudio. From there you can configure an install type (set it to silent & it will not need switches), import reg files and choose if the msi is standalone msi or wrapped with setup.exe You can also add extra addons like plugins if a proggy uses any. But really, you need to read MS's MSI faq and such to really do anything worthwhile. Go to MS and get the MSI SDK.

this is all good, but i prefer wininstall le, this thing is powerful and it allows you to edit the files created directly so you can see what goes on.

I agree WinInstall is powerful, but slow for me (esp. loading in the beginning) and AdminStudio or just DevStudio is a more complete package. WinInstall LE edition being free however does make it a (the) top contender for freeware, though i find MaSaI being easier and quicker to work with in terms of manipulation. Quite truthfully, I use a whole bunch of different editors and util's (MakeMSI, WIWW, WICLIB, Distrubuter, etc) depending on the situation.
