Finally I got some time to install the accelerators on the CRM VPC 4.0 of Microsoft. The CRM Accelerators are availbable for download on CodePlex. These accelerators are currently available for download:
Extended Sales Forecasting
Enterprise Search R1
Newsfeed Business Productivity
The CRM Accelerators are released on November 6th 2008 and updated on March 6th 2009, so enjoy using the accelerators.
