First time EXE

Hi, I am curious, how to create a setup MSI/EXE for the first time install so that user installs it and recieves updates via WyUpdate? Thanks and regards, Pooran

Are you talking about creating your installer? As of wyBuild 2.6 we don't integrate the installer creation. However, there are a few good options:

We recommend NSIS. Tell me if this helps.

How to deal with uninstall done by installer when updating/adding files to install directory or adding registry keys by wyupdate?

That's an excellent question. We'll be writing help article about this soon, but you simply call this from your uninstaller and wyUpdate cleans all newly created file/registry since the fresh install:

wyUpdate.exe /s /uninstall

or in NSIS code:

;Clean up any files, folders, and registry created from updatesnsExec::Exec '"$INSTDIR\wyUpdate.exe" /s /uninstall'
