The Test Management System requires version 4 of the .Net Framework to be installed, the easiest way to identify if you have the .Net Framework 4 installed is to attempt the installation. If you see are message displayed:
You do not have the .Net Framework 4 installed, please visit http://www.microsoft.com/downloads/ to download and install it.
You must install the 4 framework.
When installing the .Net Framework 4 you have two options - either installing from a "web download" (a small download, which will then install only the components you require) or you can download a "redistributable" which is a large file containing all the files necessary for the .Net Framework 4 to be installed on any machine.
If you plan on installing the Framework on more than one machine within your organization it is suggested that you use the redistributable, to avoid multiple downloads.
The web downloader can be downloaded from:
http://www.microsoft.com/downloads/details.aspx?FamilyID=333325FD-AE52-4E35-B531-508D977D32A6
It is approximately 3mb in size.
The redistributable can be downloaded from:
http://download.microsoft.com/download/6/0/f/60fc5854-3cb8-4892-b6db-bd4f42510f28/dotnetfx35.exe
It is approximately 200mb in size.
Please note that Enterprise Tester also uses some libraries from .Net 3.5. These libraries are included in the Enterprise Tester installer from V4.3 and above. In some circumstances, you may be required to install .Net 3.5
