I am working on WPF C# 4.0 project in which I am trying to print a RDLC report which is basically an invoice directly without displaying the ReportViewer. I refered code from the following MSDN link and modified it for my purpose.
Following is the modified code which I am using.

Code which Invokes Run Method
Classes.DirectReportPrint drp = new Classes.DirectReportPrint();
drp.ReportTable = Classes.Class_Sales_Bill.GetBillDetails(this.saleObj.Row_ID);
drp.Run("POS.Reports.Rpt_Anil_Sale_Bill.rdlc", "DataSet1");
This code works well when I am using Visual Studio debugger to execute it. However, it fails if I publish my project, install its setup and then try to run its exe (Weird Behaviour).
If I run exe it works for the first invoice which I try to print. For the subsequent invoices I get the following error.
An error occurred during local report processing. Access to the Path 'c:\Users\Rpt_Anil_Sale_Bill_0.EMF' is denied.
Here Rpt_Anil_Sale_Bill is the name of my RDLC file.
On further digging I identified that the exe code creates an intermediate EMF file in this path C:\Users\Nilesh\AppData\Local\Apps\2.0\BWQ6XD5A.DB0
If I try to open this file I get the following error:
Need help in identifying what's going wrong with the code.
Any help is appreciated. Thanks!!
