Repetitive Installations
In order to avoid installing multiple copies of Adobe PDF Library on your machine, InstallShield detects
whether a previous copy of this Adobe PDF Library version is already installed. If so, it will need to
remove it before proceeding with the new installation release, via the following popup:
Accepting the Confirm Uninstall prompt will clear the previous copy of the release from the machine,
ending with this completion screen:
At this point you must re-start the installation by again locating and double-clicking on the Setup.exe
program.
NOTE: InstallShield prohibits only duplicate copies of the current version from
residing on the machine; it does not prohibit prior releases. However, you should
ensure that any prior releases are either isolated from the current environment in
some manner (e.g. if they must be retained for backwards-compatibility or
regression testing) or uninstalled in order to prevent inadvertent conflicts with the
new release.
