I've been reading through Phil Wilson's The Definitive Guild to the
Wndows Installer
<http://www.amazon.com/Definitive-Guide-Windows-Installer-Experts/dp/159

=8-3> . I got the distinct impression, though I can't find it now, that
rollbacks cannot happen during the Install Finalize action, let alone
after Install Finalize. Various experiments would back this up even. I
can, and I currently am, returning an error code that causes the MSIExec
to stop and return an exit code after Install Finalize.

But the action doesn't roll back.
<InstallExecuteSequence>
<Custom Action="schedConfigMods.action"
After="CostFinalize" />
<Custom Action="findIceFramework.action"
After="InstallValidate" />
<Custom Action="rollbackConfigMods.action"
Before="execConfigMods.action" />
<Custom Action="execConfigMods.action"
After="InstallFiles" />
<Custom Action="generateConfigurations.action"
After="Install Finalize" />
</InstallExecuteSequence>
This action needs to run after the files have been written to disk and
after the "execConfigMods.action", but I don't seem to have that
granular of control. If I set the After attribute to
"execConfigMods.action", the "generateConfigurations.action" runs before
the files are written to the disc and the install exits without error.
Right now, I want the install to fail and roll back, but it is defying
me.
If I look at the log, all of the files actually get written to the disc
during Install Finalize and the first file copy doesn't happen until 23
lines into the action.
Thanks!
Rory
