Can't Uninstall v.6.4.2.3788

[Ahmaddba 0]

I have evernote v 6.4.2.3788 installed on my pc and want to uninstall it & then again install the latest version . 

I have missed evernote.msi file . Another file evernote.msi v6.5.4 is there and it can also installs second new Evernote on my windows 8  . Can anybody help me in this regard?

If i try downlaoding same old version and run it. it says this is already installed uninstall the previous version and then try to install. and if i try to uninstall it doesnt works as there is no evernote.msi file for that specifi version.

Thanks
