Error while opening document in WPF application

161 Views

Hello.

Im having error while opening CR document in client computer.

I know that I need to install package in this pc, but not really sure what else can help me, becouse far i have installed:

CRRedist2008_x64.msi

CRRuntime_64bit_13_0_4.msi and nothing really can help me.

My app is wrote in VS2010 pro, this is way im opening document:

ReportDocument rep = new ReportDocument();

rep.Load("../../SzablonyCR/DokumentFV.rpt", OpenReportMethod.OpenReportByDefault);

rep.Refresh();

rep.SetParameterValue("@par", docID);

viewer.ViewerCore.ReportSource = rep;

Of course in client pc i have folder named "SzablonyCR".

For doument im using stored procedure, thats why there is "@par , INT" parameter.

While opening document still getting this error:

Specified cast is not valid

InerException:
