Compilation Error : Could not load file or assembly CrystalDecisions.Web, Version=13.0.2000.0

I have just downloaded an application from TFS and it gives error on build: Could not load file or assembly 'CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) The application is working fine on my colleague's machine. I checked the bin folder and it has the CrystalDecisions.Web.dll file. Changed the version from 13.0.2000 to 13.0.3500. That worked for this file but then getting same error for CrystalDecisions.ReportAppServer.ClientDoc. Changed the version for this file too but that didn't work. So reverted everything back to original. Tried few other options suggested on net but nothing seem to be working. This is first time I am working on an application involving Crystal Reports, so not sure if I need to download any related package explicitly. Please advise.
