Post From: I need to uninstall and to re-install Sierra Chart platform on my PC.

Dear Support,

This morning while loading up my Sierra Charts, I got a message from my computer security that something was wrong and that a mal-user could take control of the app.

Sorry I forgot to take a screenshot of the message as I panicked and tried to close it down asap.

I think I need to uninstall, Sierra Chart - and to-re-install it again. Please let me know how to uninstall first - as my downloaded version of SC is not listed in the usual 'installed apps list' in Windows 11.

Thank you for your help.
