I would like to inform you that our web installer supports the following versions:
Windows Vista, Windows 7, Windows 8, Windows 2003, Windows 2008
When you try to make the installation using the web installer and the OS is not compatible the checkbox for selecting Sitefinity is disabled.
In this case you need to use the Project Manager in order to install Sitefinity 7.1. You could download it by following the steps below:
1. Go to your account in Sitefinity.
2. Select Products & Subscriptions and click Sitefinity.
3. Download installer and other resources.
4. Browse all product files
There will be support for versions: Windows 8.1, Windows 2008 R2, Windows 2012 soon.
