This is a short tech tip for working with the OpenInsight RTI_CDOMail function. I recently uncovered a situation where the function was returning "Error at step create No control specified" when trying to send email from a newly setup workstation.
After a comparison of the workstation environment it was discovered the clientsetup.exe program had not properly installed all of the required client setup components. The package "Revelation Software .NET Components v9.4.0" was missing from the workstation's Programs and Features list. The version of the Revelation Software .NET Components should match the version of OpenInsight.
Adding the missing programs and features component was as simple as running 'revelationdotnetsetup.msi' from the root OpenInsight directory to resolve the error when calling RTI_CDOMail.
