When trying to run an integration in GP2010 (after just upgrading from 9.0), you may receive the following error:
Log Report Failure
Could not load file or assembly 'Microsoft.ReportViewer.WinForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
The latest versions of Integration Manager now incorporate the ReportViewer Control for displaying the different reports generated by the application.
If you receive the above error, install the ReportViewer Redistributable component from one of the following locations:
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=21916 (Visual Studio 2005 components)
or
http://www.microsoft.com/download/en/details.aspx?id=6576 (Visual Studio 2008 components)
The latter will work just fine with Microsoft Dynamics GP 2010 or 2010 R2.
It is also recommended to install the 2007 Office System Driver Data Connectivity Components, which can be downloaded from:
http://www.microsoft.com/download/en/details.aspx?amp;displaylang=en&id=23734
or
Microsoft Access Database Engine 2010 Redistributable, which can be downloaded from:
http://www.microsoft.com/download/en/details.aspx?id=13255
Keep in mind that the above are not a substitute for Microsoft Office and are just intended to facilitate the transfer of data between existing Microsoft Office files such as Microsoft Office Access 2010 (*.mdb and *.accdb) files and Microsoft Office Excel 2010 (*.xls, *.xlsx, and *.xlsb) files to other data sources such as Microsoft SQL Server. Connectivity to existing text files is also supported. ODBC and OLEDB drivers are installed for application developers to use in developing their applications with connectivity to Office file formats.
Once done, reboot the machine.
Until next post!

Glad to know this was able to help.
