The script command

     writeprivateprofstring BlockedActivityList

is not used to unhide hidden applications.

Please elaborate in more details what you want to do and what is shown on the device screen or in the log tab of your device in the MobiControl web-console.

Hello Raymond,

I have used the script to enable native applications even for public applications that were also hidden, the script was sent to several devices of the same model, in some they were shown and others were not, and in those devices that do not show the applications they return an error message.

This is the error message that the device returns every time I send the script

I did the test sent this other script and the result is the same.

Hi Walter,

Your first post using terms like "hide" and "activate" caused confusions.    Based on your log screenshots in the last post,  I can confirm that you actually used related script commands to change the application-run-control (ARC) whitelists/blacklists.  This use is proper, but your terminology used is inaccurate and misleading.

Without the details of the sequence/history and actual arguments used in the script commands, it is difficult to nail down why you have problem in some devices and not in others.   In general,  some related options in feature-control and lockdown-menu, together with the current states of ARC parameters on a device, will affect the overalll application run control policies.  The syntax and argument(s) of your script command may also affect the overall results.   

So, if those devices that have problems are in different device group or have different FC/lockdown and/or have different deployed ARC script command history compared to those devices with no problem, then you have to find out which difference actually causes the problem.
