When I try to run the Virtual Flexpendant Ommicore, it doesn’t work. It asks me to associate an application to start it. Any ideas to fix it? I have completely uninstalled and reinstalled RobotStudio.

Hello, On Release Notes, you can find this: #### Required Software Microsoft Windows 10 Anniversary Edition or later, 64-bit edition, is required. The Windows App Installer is a pre-requisite for the virtual OmniCore FlexPendant software, see [https://www.microsoft.com/en-us/p/app-installer/9nblggh4nns1](https://www.microsoft.com/en-us/p/app-installer/9nblggh4nns1). The App Installer is a default built-in app in Windows 10 and later, but may have been removed on some PCs. Sideloading of apps must be enabled on Windows to install the virtual OmniCore FlexPendant.
