Just got the Windows Phone 7.1 Developer Beta SDK installed today and it's great to see lot more APIs than the earlier version.
In fact, I got the Developer SDK installed on 3 different machines.
- A new Virtual Machine with Windows 7 Professional without Visual Studio 2010 pre-installed.
- Machine with Visual Studio 2010 Professional SP1 installed.
- Machine with only Visual Studio 2010 Ultimate installed
The installation on the Machine 1 went on smooth and so did the installation on machine 2 with Visual Studio 2010 Professional SP1 installed, but was struck up with the following 'prerequisite missing' message on Machine 3 .
“Microsoft Windows Phone Developer Tools 7.1 (Beta) – ENU
Setup has detected that this computer does not meet the requirements to install this software . These requirements must be met before you can install Microsoft Windows Phone Developer Tools 7.1 (Beta) – ENU .
Setup has detected that Visual Studio 2010 Service Pack 1 is not installed on the machine for following products . Please install and retry
* Microsoft Visual Studio 2010 Ultimate .”
So guys , in case you have Visual Studio 2010 already installed on your machine , make sure you have the SP1 installed too before installing Windows Phone 7.1 Developer Beta SDK
