Due to this error I was unable to make a regular update. I had removed Evernote totally (all files, folders, registry keys, etc.). Unfortunately it turned out that I am unable to make clean installation either (so for now I’ve lost Evernote for Windows). I was trying to do it as a regular user, as an administrator, for all users, only for me, every combination possible – with the same error at the end. I have absolutely no issues with other applications with MSI installer. I don’t have any MSI-related policies applied. It is a bug in Evernote's installer.
Error from the installer:
The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755.
Error from bootstrap:
Setup error: (.\Bootstrapper.cpp:984) 0x643: Fatal error during installation.
My OS: Windows 10 Enterprise version 10.0.17763.864
I use tons of different software, I’m testing/comparing UX/UI features, so I’m installing/uninstalling lots of applications every week. Evernote setup is the only installer I have issues with. So I don’t think it is a “Windows problem”. It is a serious bug in Evernote introduced in 2015 or even earlier.

No workarounds described in above topics works for me.
