Am getting Error code 131 (Update Conflict Error) while trying to update my Robohelp 2019.0.12 to the latest update which is available. Below is the screenshot of the error for your reference.
Did you try closing RoboHelp and then clicking Continue?
Yes, the installer is really annoying as you have to start the update from Robohelp, then close all instances of Robohelp, otherwise the installation fails with that error.
I've also found that sometimes RH2019 New UI gets a bit confused and leaves processes running in the background. So if you did close all RH instances and still get the error, you might need to go to Task Manager and end the rogue tasks.
Yes, Closed all RH instances. Also in Task Manager
Please confirm you have followed these steps exactly after a reboot of your machine and still get the issue.
If that does not solve it go to https://www.adobe.com/support/robohelp/downloads.html and download the update. Unzip it and make sure RoboHelp is closed. Run that installer.
BTW. You must have admin rights on the machine.
