Cannot use user commands in Dyalog APL

I just installed Dyalog-APL 18.0 on my windows(Windows 10) machine and when I tried using ]box on -style=max on the IDE I got the following error:

FILE ACCESS ERROR: C:/Users/<User>/Documents/: Unable to read directory status

Then I noticed that there was a previous error when opening Dyalog which I had blatantly ignored:

SALT initialization failed: C:/Users/<User>/Documents/: Unable to read directory status

Furthermore, I realized that all user commands give the first error.

Some details: I installed it as an administrator privilege with Avast Antivirus installed.

Things I tried:

  1. Adding the documents folder as an exception in the antivirus setting and also adding it in the allowed apps list(from Ransomware Shield). It was followed by a restart after the change.
  2. Reinstalling
  3. Starting Dyalog as administrator
Solution

  • After some experimentation, we determined that the issue was something restricted being located in the Documents folder. By default, the APL system will look there for custom user commands:

          ⎕SE.SALT.Set'cmddir'
C:\Users\<User>\Documents\\MyUCMDs;C:\g\link\SALT\spice;C:\d\SVN\salt\trunk\spice

    So we asked it to permanently skip that location:

          ⎕SE.SALT.Set'cmddir -p C:\Program Files\Dyalog\Dyalog APL-64 18.0 Unicode\SALT\spice'

    And that solved the problem.
