Hey folks,
At my place of employ we recently rolled out several fancy new Epson interactive projectors and, with any equipment roll-out, they needed some software. So, with my fresh copy of the Easy Interactive Software downloaded form the Epson website I quickly set about building a package.
Except none of the normal switches worked.
I eventually discovered that when running the installer it is a program within a program and the shell program silently unpacks the actual content into my user profile’s temp directory (C:\Users\UserName\AppData\Local\Temp). I could see before it was an InstallShield installer but now that I had the actual files I was in business!
Except the usual “Setup.exe /s” didn’t work.
What I ended up having to do is run “Setup.exe /r” to run through the install in what is called a ‘record mode’ and at the end it generated a response file named Setup.iss in the Windows directory.
I grabbed this file, placed it with my found install files and when I ran the “Setup.exe /s” again it installed as it should. I have not tried it yet but it should then be possible to generate a response file to perform a silent uninstall as well so you can run “Setup.exe /uninst /s”.
Hope this helps you!
SASK IT GUY 
some setup.exe like an uppercase “S” vs lowercase “s” when using the silent switch.

That is very true, but unfortunately in this particular case the needed file to do a silent install was not created/included in this software so it had to be made.

Yeah, some installs are fickle like that. 😀

For any who are wondering, he literally means the “Windows” directory. I followed a set of instructions on another site that wasn’t as clear, and pulled the setup.iss file from the Program Files\ location and it didn’t work for this purpose.
Kinda janky there, Epson.
