Hi,
I have some questions about how should i manage new application versions on
the installer, if anyone could help i would really appreciate it:
- How does install works, i see i have the product GUID, the Version and the
UpgradeCode, how does the installer manages those attributes ?
- How do i know if the user had the application installed and is upgrading
or reinstalling the same version ? (i want to be able to backup and restore
some files if that is the case)
- Is the previous version automatically uninstalled before installing a new
version, are the files that changed replaced, the new files overwrite the
old ones?
Thanks,
Ricardo Lopes.
