Those are the common issue with the installation of Talend Data Preparation Free Desktop (Data Prep for short) on Windows, and how to solve them:
Windows version: we support from Windows 7 but it must be in 64 bits. We don't support 32 bit Windows sorry! (ok granted, I didn't really solve this one...)
The installer won't start: we ship Data Prep as a standard self-executable Microsoft Windows Installer. We found out the security policy in some enterprise may stop the installer from starting. Not a problem: use the zip installer instead; see below.
The installer starts but it prompt you for local administrator privileges, and you don't have them, and nobody from IT will help. Not a problem either: the zip install is your friend.
All right, so zip installer to the rescue. It's easy, follow those steps:
Go back to the download page http://www.talend.com/download/talend-open-studio#t8
Scroll down all the way down to the end until you get to the "other releases" table
These are actually _variants_ of the same release. The last line of the table should list a file like "Talend-DataPreparation-Free-Desktop-windows-1.0.zip". This is what you want. Click on the "US" or "Europe" link in the last column to trigger the download.
Unzip this zip file anywhere you like.
The application is inside: just double click on the .exe -- and you are all set!
