Hi Folks

I have a Custom Installation Class (that inherits from
System.Configuration.Install.Installer)

Basically during a file copy, if it errors I want to roll-back the
installation.

Can I initiate the roll-back from within my custom installation class.

The error I am trying to catch is during my overridden Commit Sub.

Regards
Jon

Try throwing an InstallException. That should do it.

Unfortunately that doesn't appear to have the desired effect.

It throws up an exception message and says that installation will
continue but the application will not function as you might expect.

Any more ideas would be very welcome, I just need to figure out how to
abort the installation and rollback (from a Custom Installer Class)

Jon

It's because you're in the Commit method - that means the installation
transaction is finished. That's what Commit means. If you want it to roll
back you need to be in the Install method.
