This is particularly problematic when permissions set on plist entries or files prevent the successful installation of new installs and/or updates. While most installs, uninstalls, and updates operations happen without incident, there are cases where a user may not be able to complete such tasks due to some registry or file conflict on the machine.
The Adobe Reader and Acrobat Cleaner Tool removes a standalone installation of Reader or Acrobat, including any leftover preferences and settings remaining after a standard program uninstall. Always uninstall DC products via standard, supported methods. Adobe provides the utility as a least resort to repair machines after a failed or partial uninstall.
The AcroCleaner is not an uninstaller and should NOT be used as such.
