Reed Me : Bing: there it is! My PPS setup problem(s) solved.

 
Some tricks to setting up PPS with SQL 2008.

Obligatory bing plug. The name is growing on me... Link #1 in the search results was Nick Barclay’s great post on sorting out PPS setup issues with SQL Server 2008:

"System.Web.Extensions" performancepoint "configuration error" - Bing

Useful reference linkages:

• Installing and Troubleshooting M&A on Win / SQL 2008
• Install PerformancePoint Monitoring Server with SQL Server 2008 (TechNet)
• ASP.NET AJAX 1.0 (the missing piece what was causing the problem)
