Hi,
this is not directly LimeSurvey related, but SPSS.
Do you use a Mac?
You should search the internet for the issues of Mac OS Catalina and IBM SPSS, e.g.
developer.ibm.com/predictiveanalytics/20...atalina-macos-10-15/
But there is a workaround.
The dat-file is a simple comma-separated csv-file .
This you can import into SPSS. (something like "Read text")
After that you run the syntax (only VARIABLE LABELS, VALUE LABELS and RENAME).
Maybe you have to adapt the dat-file, but you will be able to import.
