Workflowgen 7.0 - Numeric Data Parameter

1

Hi ,

We are not able to create process instance in Workflowgen 7.0 when we have workflowgen process with numeric data parameter . We got following exception from workflowgen. We don’t have .Net framework 4.6 on workflowgen server and we have only .Net framework 4.5.2 on workflowgen server. Please guide me how to solve this error.

ProcessInstanceStart has thrown an error: Method not found: ‘System.String System.String.Format(System.IFormatProvider, System.String, System.Object)’.
System.Exception: ProcessInstanceStart has thrown an error: Method not found: ‘System.String System.String.Format(System.IFormatProvider, System.String, System.Object)’.

Hi Santhosh,

To solve this error, you need to install .NET Framework 4.6.1 or higher on your web server.

It is a system requirement of WorkflowGen 7.0.0 and higher:
