Baris's SharePoint Blog

For the last SharePoint 2013 Installation I used the AutoSPInstaller. After putting all required files into the PrerequisiteInstallerFiles folder and starting the Installation the .Net 4.5 Framework installed continuously and rebooted the server. After some digging I found out that SharePoint requires .Net 4.5 Version 4.5.50709 but I had a lower version installed. You can see the installed version number in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full Just download the newest .Net 4.5 installer here  and install it manually or put the offline installer into the PrerequisiteInstallerFiles folder.
