Q: Many of our enterprise users have reported problems running the X12ARIMA functionality (e.g. seasonal adjustment, etc.) on their work computer.
By default, NumXL installer program places all files in a sub-folder under %AppData% (i.e. c:\users\<username>\AppData\Roaming\NumXL). This is a common practice for installing software on per-user basis, and does not require an elevated administrative permission for installation.
In many environment, the MIS/IT folks implemented strict software restriction policies for their users' %AppData% folder (and sub-folders) to prevent potentially harmful programs from running in those folders.
Unfortunately, in such environments with strict software restriction policies for %AppData%, the X12ARIMA programs could not be run and such, render the X12ARIMA functionality inoperable.
We recommend our users to move the installation directory outside the %AppData%, by simply re-installing NumXL, but this time, select a different installation directory (e.g. C:\NumXL) from the default one.
