We have released an early build of Active911 for Windows PCs. All of the base functionality is in place which will give us a good foundation for future updates. There are still features that we plan on adding and there may be some strange bugs in these early stages. If you would like to give it a try, you can find all the information you need at: http://wiki.active911.com/wiki/index.php/Beta_Testing#Windows_PC_Beta_.28Windows_XP_through_Windows_10.29 under the Windows PC Beta heading.
There is also a PC App category on our forums for you to share your experiences with the PC App: http://community.active911.com/discussion/543/pc-app-beta#Item_1
