Hi Sello

I am using K2 service account to deploy the solution

I was finally able to deploy entire solution successfully. There was a project with Form Generation Event. After isolating this project file, I had to re-add this event which did the trick.

Install Web Deployment Projects 2010 from http://www.microsoft.com/download/en/details.aspx?id=24509 will fix the issue
