**Event log:**

This happens almost every time we install the client under Windows 8 or Windows 10, whether over network drive or local drive.  
Everythings seems fine after the error message is dismissed. But with a silent install this is annoying.

Hi @VincentVegas,

Thanks for your feedback,

Are you using the desktop app (64 bit) downloaded from [this page](https://about.mattermost.com/download/#mattermostApps)?
