Best way to run old-install uninstaller?

Hi all,

I release new versions of my software quite often.

Whats the best way of the new version NSIS installer uninstalling the older installed version first?

I hope that makes sense...

Thanks all.

Use Exec to execute the old uninstaller if there is one. If there isn't you can use RmDir /r to remove a whole folder, or Delete for individual files.
