Annoying error when configuring the Commerce Data Exchange service

Sometimes it is easy peasy … and sometimes it is not. This one leans towards the not and does it in an annoying way.

I was running the PowerShell script for configuring the Commerce Data Exchange. It prompts you for user, password, path for the binaries and the certificate thumbprint … not anything complicated. And although I had knew that I had done it successfully before I was stuck with this error:

Get-Content : Cannot find path 'C:\inetpub\DynamicsAxRetail\CommerceDataExchangeRealtimeService\Web.config' because it does not exist.
At C:\Program Files (x86)\Microsoft Dynamics AX\60\Commerce Data Exchange\Real-time Services\6.2\Sample Deployment Scripts\InstallCommerceDataExchangeRealtimeService.ps1:713 char:34
+         $WebConfigXML = [XML] (gc <<<<  $WebConfigFilePath)
    + CategoryInfo          : ObjectNotFound: (C:\inetpub\Dyna...vice\Web.config:String) [Get-Content], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetContentCommand

I tried several times. Restarted. Tried again. Tried as another user. Tried beating my head against the wall. Nothing seemed to be working.

The solution was deleting one character from the binary path. I just used

C:\Program Files (x86)\Microsoft Dynamics AX\60\Commerce Data Exchange\Real-time Services\6.2

instead of

C:\Program Files (x86)\Microsoft Dynamics AX\60\Commerce Data Exchange\Real-time Services\6.2\

and after removing the backslash at the end of the path string it installed without any problems …. Grrrrrrr …..
