IM error: Could not load file or assembly ‘Microsoft.ReportViewer.WinForms’
After upgrading to a GP 2010 or GP 2013, you may receive the following error when using Integration Manager:
Could not load file or assembly ‘Microsoft.ReportViewer.WinForms, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
With the end of the support lifecycle of Dynamic GP 10 and the release of Dynamics GP 2013, a lot of companies will be upgrading from older versions within the next year. Integration Manager also needs to be upgraded at that point, and it does have a few changes from the older versions. One of those changes is using the ReportViewer Control for displaying different reports that IM generates, including log files.
While there are a number of applications that install this software automatically, some workstations may not have this installed which will result in the above error. The fix is simple; just download and run the ReportViewer.exe file from the link below to get the ReportViewer Control installed.
