However, my most recent problem with Integration Manager did actually produce a useful error message:
Integration 'Invoices' is not ready to run due to the following problems:
- The destination could not be initialized due to the following problem:
Cannot create ActiveX component.
I did a search and found a most useful KB article from Microsoft which detailed the problem (Microsoft Dynamics GP hadn’t been written to the registry correctly) and also the solution.
I read the whole article and decided to try a shortcut of starting with step 3 of re-registering the Dynamics.exe. To do this open a Run or Command Prompt and type the following (this particular problem was encountered with Microsoft Dynamics GP 20103 R2):
"C:\Program Files (x86)\Microsoft Dynamics\GP2013\Dynamics.exe" /regsrver
When I retried the integration, it ran through without further problems.
