There is not a way, that I know of, to uninstall an Evo/DBA update.
The only way to go back is to restore en entire \DBAMFG folder from backup.
Any data that was enter will be lost.
We have been working with DBA/Evo since 2001? 2002?, if there is something we have learn is that updates do not always work.
There has been lots of times where updates fix something but brake something else.
What we do is to install the updates on a virtual machine.
We use Oracle VM VirtualBox (
https://www.virtualbox.org/ )
It is free, and very fast.
We have install WinXP, and Pervasive 10. It is a very quick installation and it has proven to be
an excellent way to test updates, new features, and existing ones.
if you need help with a Virtual Box just ask.
