PPS M&A requires AJAX v1.0 installed. Well, recently Microsoft released the .NET Framework 3.5 which includes the AJAX. Well, on a couple of my server rebuilds using .NET Framework 3.5, SharePoint runs just fine.
But, when I install PPS M&A, it crashes the SharePoint page on startup. When I uninstalled .NET 3.5 and used the AJAX v1.0 installs, PPS and SPS fired right up.
You have been warned…
