How do I fix the "Resolve.msi" error for Davinci Resolve?

insert the install disc.
if it's asking for the msi, that is the installation media.

I know it's a large download but it probably would be better to uninstall and reinstall it. The best way to clean it out is to use the free versions of IObit Uninstaller and Everything from voidtools.com IObit does an excellent job of uninstalling software,better than Revo Uninstaller. Everything is a search tool that looks for any remaining files and such that you can delete. Just open it,wait for it to load up and type Davinci Resolve in the toolbar and it will load what's left which probably won't be much.
