If I’m understanding correctly, you’re wanting to install the Mattermost Desktop App?
Have you tried installing from this page? If you have tried this, could you explain in more detail what the exact issue is that you’re experiencing and the steps you have followed so far?
Hi akhil.mekala and welcome to the Mattermost forums!
Can you please describe in detail what you tried and what you were seeing? I.e. from where did you download what file, how did you try to install it and what error messages (if any) did you receive?
