After I downloaded the installation program for the application, I was prompted that there is no application associated with the file. Please install the application. If you want to install, you can create an association in the “Default Application Configuration”. According to online accounts, I modified the local group policy, but the error reported still exists, which prevents me from installing the application properly. My system is 22H2 for Win11 Home Edition. The problem is quite urgent, I hope we can find a solution soon
Error encountered during download and installation, resulting in inability to download and install
Did you try downloading the installer again? And are you downloading it from https://obsidian.md?
