Hi, I have just replace an assembly file in my solution. The new assembly is Microsoft.ReportViewer.WinForms version 11.0.3366.16 to replace the old version 10 assembly file.
The reason behind was to support excel exporting maximum row supported from .xls(max 65k) into .xlsx(max 1 million) rows. I have tested in my local PC and I have no problem save as .xlsx file and view in the .xlsx file.

But when I try on another PC, it return me the error as above title whenever I access the RDLC module. I have checked all my configuration(folder referencing, Copy Local as true, Specific Version as true and both PC have SQL Management Studio 2008 installed). The only difference is workable PC has Visual Studio 2010 installed while unworkable PC do not have Visual Studio 2010 installed.

Is there anything that I have missed out? Any help would be appreciated. Thank you.

What I have tried:

1. Changed all necessary configuration needed.

You'll need to install the report view runtime on the target computer to ensure that all of the dependencies are present.

Download MICROSOFT® REPORT VIEWER 2012 RUNTIME from Official Microsoft Download Center[^]

Yes sir, I have installed that but seems like the targeted PC is missing other components too plus the targeted PC is running on Windows XP(at least Windows 7 is needed for Report Viewer 2012 Runtime). Anyhow, thank you for your help and I will mark this as answer. Thank you.

Actually, Vista SP2 is listed as the minimum, although Vista will no longer be supported from 11th April.

Support for XP ended in April 2014.
