I am using QBXML SDK to connect to quickbooks from visual studio. It was working fine and updating invoices till yesterday when I installed the quickbooks update. After Updating quickbooks, its showing the following error:
System.Runtime.InteropServices.COMException (0x80040408): Could not start QuickBooks.
at Interop.QBXMLRP2.IRequestProcessor4.BeginSession(String qbFileName, QBFileMode reqFileMode)
at QB_Process.API.ProcessRequests.Process(String operation, String strXML)
Whats wrong?
This issue was with permissions and not with the update. In the task scheduler, I changed the user group to administrator and its working now...
