How to override the crystal report error?

Question

I have a crystal report which is having a data source from sql server .I am always getting this error when we want to show the report.I have seen the connection too.No Problem with that connection.

error :

Unknown Query Engine Error
Failed to open a rowset.
Error in File C:\Users\ADMINI~1\AppData\Local\Temp\student{ED5C2412-C7A1-4E1D-8093-1EFDA02340ABD}.rpt:
Unknown Query Engine Error

Can any one help me ?

In extension to this Question I found a problem was caused by one column of the table in the report when i remove that fields it is working fine.When the report is migrated from access to sql server source it is converted using cross join.Does this raised from table linking only ?

I'm sure if this is relevant but try the solution given in this link . The solution suggests you add this line to your config file :

<startup useLegacyV2RuntimeActivationPolicy="true"><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
