Hello,
My understanding of msiexec [msi] /qb or /passive is that the
effect is much like if a user had accepted/defaulted all of the dialogs
and continued through the installation process without stopping for
coffee, tea of any other refreshments. I'm facing the problem where my
understanding is obviously lacking. We have an installer where in the
event of it's execution in Full UI mode, it updates and installs our
software as expected. On the other hand in the event that we run the
installer silently, only the files that have been changed between the
previous installed version, and the new one are left, while all files
that are not modified get wiped out.
I believe this is happening due to RemoveExistingProducts, and:
<RemoveExistingProducts After="InstallFinalize" />
The question(s) I have is why would it not happen equally in Full UI and
and Basic, and how do I stop it from wiping out the previous version?
Thank you for your time,
G
