Error: The Melissa Data CASS engine appears to not be installed (can't find dll)
***CASS is only avaliable with a spatial license. If you would like to trial CASS please reach out to your Alteryx Sales Account Executive.
Reasons for this error message:
CASS data has yet to be installed on your machine and you are using a tool requiring CASS data (Business Match Macro (CAN) & (US); ConsumerView Matching Macro; Canada Geocoder; CASS; Parse Address; Street Geocoder; US Geocoder; US ZIP9 coder).
CASS has expired.
Mismatched between registry entries or install folders.
Not installing the CASS file correctly
Use the download links (see 'How to download CASS' section below) to run the CASS download and extract the files to a location on your machine (You can use the same location as the previous install). Run the Datainstall.exe in the CASS download folder (Screenshot below).
This will take you to through the installation of the latest version of CASS. Click 'Next' all the way through the install of the latest data to the unistall section. When you get to the uninstall screen please make sure the previous versions of CASS are selected (Screenshot below).
Once selected press 'Next' , select the local directory or network install location and press 'Finish'. Click 'OK' when it asks if you are sure you want to delete the previous versions of CASS. Once CASS has installed hit 'Close' in the CASS installer.
The 'The Melissa Data CASS engine appears to not be installed (can't find dll)' error should now dissapear once you open a new instance of Alteryx.
If the error does not dissapear it may be because some of the extracted files from previous CASS versions have remained on the machine. If so, you can delete all CASS files manually from your windows explorer, and then reinstall the latest data again using the process outlined above. If you are unsure where you extracted and saved the CASS files, type CASS into the windows explorer search function and follow the file path.
How to download CASS:
