Question:
I am experiencing an issue running the X12ARIMA functionality, including seasonal adjustment, on my work computer. This functionality works perfectly on my personal computer.
Answer:
Although the NumXL installer program places all files in a subfolder under %ProgramFiles% (e.g., C:\Program Files\NumXL), the X12-ARIMA functions implementation requires running a batch file located in the end-user's local profile directory (i.e., %AppData%).
In many environments, the MIS/IT personnel implemented strict software restriction policies for their users' %AppData% folder (and its subfolders) to prevent potentially harmful programs from running in those folders. As a result, in environments with strict software restriction policies for %AppData%, the X12ARIMA programs cannot be run, rendering the X12ARIMA functionality inoperable.
Resolution:
The good news is that starting with NumXL version 1.67 (MARTHA), NumXL supports the latest U.S. Census X13ARIMA-SEATS seasonal adjustment software and is not required to run from the user's local profile directory so that it will work perfectly in environments with strict software restrictions.
We strongly recommend that all our users utilize the X13-ARIMA-SEATS and migrate their existing X12 models to X13, as the U.S. Census no longer maintains the X12ARIMA seasonal adjustment software.
