How do I fix "Package Installation Failed: UnspecifiedError" when trying to install RobotWare add-i

in RobotStudio
I've installed Robot Studio for the first time, and I restarted my PC after doing so.

In order to simulate a robot controller, I need a RobotWare Add-In.

When I try to add it, all I get is : "Package Installation Failed: UnspecifiedError"

How can I fix this?

Thanks,

    Hello there,

    Which RobotWare version are you trying to install?

    Can you double-click the error and provide the description that pops up (if any)?

    I just installed RW 7.8.2 without any issues.

    Hi, I'm having a similar error while installing robotware 6.15.8. I get the following error code:
