New Post: Function "Add-SQLAlias" does not add a 32bit alias

I realized today that the SQL Client Alias I have configured using AutoSPInstaller only adds a 64bit alias and not a 32bit alias. This is not a problem for straight SharePoint 2013 but it became a problem when I tried to configure Workflow Manager 1.0 on the server. It was not able to connect with the connection string I supplied because there is not 32bit alias matching the name I have in the string. WorkflowManager will not be the only thing that would need the alias, so I think having it included is pretty much a must-have.

My solution going forward for AutoSPInstaller is that I have modified the function and saved it to my "AutoSPInstallerFunctionsCustom.ps1" file. I've also pasted the modified function below if you're interested.

Function Add-SQLAlias()
