The following error message displays while attempting to install Yearli:

“You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5 SP1”.


Currently on Windows Server 2008 R2, .NET Framework 3.5 SP1 comes as a feature in Server Manager. Since this is a feature of the operating system, Windows does not allow installation during normal program installation. This feature must be installed separate from the program.

  1. Click the Start menu.
  2. Click All Programs.
  3. Highlight Administrative Tools and select Server Manager.
  4. In the Server Manager Interface, click Features.

  6. In the Select Features interface, expand .NET Framework 3.5.1 Features.
  7. Check the box next to .NET Framework 3.5.1 and click Next.
  8. In the Confirm Installation Selections interface, review the selections and then click Install.
  9. Allow the installation process to complete and then click Close.
