openPDC installation failed on an Amazon EC2 Windows VM

Hi Ritchie and Stephen,

I encountered an error when I was trying to install openPDC v2.8.196 on an Amazon EC2 Windows virtual machine. The database I installed is PostgreSQL v13.2 (x64). The installation failed at the step of configuration setup with an error message given below.

Please shed lights on this issue.

Thank you!

We are going to have to test this for you. Do you happen to know which version of PostgreSQL you are using?


Thank you! The version of PostgreSQL is v13.2 (x64) for Windows

btw, are you going to test this installation on an Amazon EC2 Windows machine too? or just do it locally?

We will test locally first, just to see if we can replicate it easily - could be an easy fix…

Finally got a build that works well:

The issue was an old version of the PostgreSQL .NET adapter that didn’t work with newer authentication methods.

Let me know how it goes…


Hi Ritchie,

Thanks for fixing it. It works like a charm. I may need to ask you more on STTP connections.
