Updating and or uninstalling single programs

[Hans Willison]

Hello,

I have installed quite an old version of the All-In-One-Installer (2016-01). Two questions

1) Do I have to uninstall the old version prior to installing the new one?

2) Can I uninstall or update a single program e.g. LDView? The only option in "Apps and Features" is to uninstall the entire suite.

Hans

PS: OS is Windows 10
