Mathematica Version 11.2 desktop / Windows 10 Pro 64-bit

Autocomplete and Information icon no longer appear.

Practicalities of Using the Wolfram Language

Is there some setting someplace where I might have mistakenly disabled it.

Thanks in advance.

1 Answer 1

Thank you all for your help.

I received the following two solutions from Mathematica Technical Support.

I used Solution 1. It worked. Fortunately, Solution 1 did not require typing in an activation key.

The next day, I received Solution 2 from Mathematica Technical Support. Solution 2 should be easier. I did not test it since Solution 1 had already corrected the issue.

Note that the following will display the User Base Directory:

Help menu | System information... menu item | Front End tab | Directories section | User Base Directory

******************* Solution 1 (Harder Solution )*******************

Thank you for contacting Wolfram Technical Support.

Can you please try these steps:

1) Close Mathematica.

2) Renaming your $UserBaseDirectory.

By default (for Windows 10), it is C:\Users\username\AppData\Roaming\Mathematica

3) Try using the autocompletion feature again.

******************* Solution 2 (Easier Solution) ******************

This is an easier process to resolve the behavior:

1) In Mathematica, evaluate

PacletUpdate["EntityFramework"]

2) Restart Mathematica

This has just been tested this morning.

    $\begingroup$ They would be more useful saying what exactly goes wrong, I have a lot of stuff in user base dir that I don't want to drop. And now I have to pick one after another to check. $\endgroup$

  • $\begingroup$ @John You can ask the support for more detailed information about offending subfolder of $UserBaseDirectory. $\endgroup$ Nov 28, 2017 at 12:39
  • $\begingroup$ Kuba and Popkov - I just updated Answer 1 with Solution 2 which is easier. Please let me know if it works for you. $\endgroup$
