xavierx Posted July 3, 2007 Share Posted July 3, 2007 I might be misunderstanding the whole concept of switchless/switches but i am not sure. My question is more just that when you are doing silent installs and unattended installs basically it just has the program all ready set up on your computer. Now what i was wondering is how it actually works does it just go next next next and finish uses the default settings and installs typical settings if you may? Programs like Office or lets say nero for example may have a custom install feature where you can turn off and strip your install of features you may not use or don't need. How does the switches work? i am not sure i fully get it i guess, switchless is basically not needing the /s and it still installs silent?So i assume programs like WPI is just another avenue instead of perhaps writing your own batch file or using the runonceex way right? But they all basically end up the same in the end result? Link to comment Share on other sites More sharing options...
cyberloner Posted July 3, 2007 Share Posted July 3, 2007 too much information for u in one days and stop ask question like that...learn ... read... try yourself... silent install only for those who want installation without asking what u want and u dun want... switches for software some have and some dun ... so if got switches we dun need to remake the installer... if dun have nero lite is born for it ( silent installation )so read read read..............

NOTS3W Posted July 4, 2007 Share Posted July 4, 2007 If we all had to learn, read and try everything for ourselves without being able to ask questions to validate our understanding, there wouldn't be much point to this forum. Switchless is switchless only in its final form. A switchless installer typically runs an installation program with certain switches, you just don't see them because they're incorporated into the switchless installer.A program's installer MAY take switches to instruct the program in how to handle its operation. But the program must be written to look for and use certain switches. You can't just throw a /s switch at any program and expect it to run silently. The program must be written to use the switch. Depending on the program and how it was compiled, the switch for a silent installation could be /s or -s or /silent or /qn or /qb or whatever. You get the idea.A program might be written to not display a welcome screen or ask you to accept a EULA if it's run with its silent switch. Or it might be written to change its default installation folder with whatever follows a /dir= switch. Not all programs are written to recognize all (or any) switches. Some will use default settings whenever they're run silently and you cannot specify much else. Others will just not install silently no matter what you do which is why some requests for silent switches or switchless installers go unanswered.A switchless installer is basically a file that wraps around the original program and contains all of the original program's files and the switches. The writer of the switchless installer needs to figure out what switches to use and incorporate them into the switchless installer. Technically, a switchless installer is a self-extracting archive. When a user runs the switchless installer, it extracts the contents, places them where they need to be and runs the original installation program with the switches it's been configured to use. For example, you might find a switchless installer named installer1.exe that will run the command program_a.exe /silent and another (installer 2.exe) that runs program_b.exe /qn. You could accomplish the same thing with a batch or cmd file containing the lines program_a /silentprogram_b /qnbut then you would have to deal with placing the original program files in the right folders. It's a lot easier to just use a pre-made switchless installer (available through the abundant generosity of some members) and let it do all of the work. Switches and switchless installers only control certain aspects of an installation. It would be diffilcult, for example, to use switches to specify the installation folder, whether or not to display welcome screens, whether to create desktop shortcuts, which skin to use, the speed something should run at, which dictionary to use, text color, etc. Instead, many programs house those details in separate settings files or in the registry. When you install manually, the program stores your responses. When you change a program's settings after installation, those data stores are updated with the new current values. Usually the only way to figure all of that out is to install the program manually and see what changes in the registry or in the program's folder. Then you could write a routine in the switchless installer that sets those things when the program is installed but each user will have their own preferences. The emphasis is on getting the software installed silently and suppressing the installation screens. The rest can be set by the individual user when they run the application.There are programs that will record your mouse movements, clicks and keystrokes to duplicate those actions during an unattended installation. As you say, they "go next next next and finish". All of the installation windows open as though you were running a normal manual installation but a macro provides the responses in your absence. It's not the same as a switchless or silent installation, but it is unattended and accomplishes the same thing. This arrangement is good for programs that don't accept switches.Switchless installers are usually run from runonce. Addons are switchless installers with yet another layer of code that allows them to be run from winnt.sif as a hotfix or update.I'm still relatively new to all of this and this is only what I've gleened in the last few months. If anyone has any corrections or cares to add anything, please feel free to do so.Ray Link to comment Share on other sites More sharing options...
xavierx Posted July 7, 2007 Author Share Posted July 7, 2007 hey thanks so much NOTS3W that helped me a bit. i will have to read more into it as far as cyberloner i assume thats why he is called that haha it would defeat the purpose of a forum if it wasnt used to ask for help and if everyone went on replying why not try it yourself.As i stated i have been reading it i just ran into a fork thats all..cyberloner: babi hutan Link to comment Share on other sites More sharing options...
