Default installation folder/files and registry settings

Oke people I like to know if I am completely wrong in asking software vendors about standard installation folders and paths (registry settings) when needed to completely clean out a failed installation.

I am asking something I should first sign a NON-disclosure form for or what.

If so where may I find this (thinking about EULA / Users Agreement).

The floor is yours.

To completely “uninstall” avast use http://www.avast.com/uninstall-utility
Why sign a non-disclosure form?
The EULA for free can be found here http://files.avast.com/files/legal/eula-avast-free.pdf

I’m not exactly sure on what you are asking nor am I sure about the reason for your poll? ???

The uninstaller fails to remove registry settings.
While it may remove the more obvious program folders I am aware the software installs also in Windows\System32.

Since I ran into problems getting the re-installation to work properly I like to know where I can find everything (*.exe, *.dll etc) of the installation so i can shift through my Windows and program files folders etc to be able to be sure I clean it out completely.

At some point I am given a line that I may not get this information as it would be against the security policies of the software vendor.

I refined the poll in the hopes I am made aware what I can or can not ask of a software vendor.
