Problems running Defraggler

Defraggler will not run. The error message "Processing aborted due to: Access Rights" appears:

You can only run Defraggler using a Windows account that has administrator rights. Either log on as an administrator, or right-click on the icon and click Run as administrator.  If you are not an administrator, you'll be able to start Defraggler, but you won't be able to analyze or defragment drives.

After you run Defraggler, there is less free hard drive space available:

When you run certain third-party programs (such as Defraggler), Windows creates an automatic System Restore point for security reasons. This System Restore point takes up hard drive space. See this topic for more information on Windows and shadow copies.

When you try to run Defraggler, you see a warning dialog box from ZoneAlarm firewall:

ZoneAlarm is a common security program. It checks for suspicious program behavior and alerts you if an unknown program starts to ask for access to system files or the Internet. If you run Defraggler for the first time when you have ZoneAlarm installed on your computer, you may see an alert from ZoneAlarm. You may also see an alert when Defraggler checks for an update.

Click Allow in the alert dialog box to let Defraggler continue. To avoid seeing any more alerts from ZoneAlarm about Defraggler, select Apply this setting to all suspicious behaviors exhibited by this application, and then click Allow.

Note: Defraggler contains no spyware or adware.

When you try to run Defraggler you see a User Account Control dialog box:

Windows uses the User Account Control (UAC) feature to prevent users from accidentally running spyware or malware or making major changes to how Windows runs (see http://en.wikipedia.org/wiki/User_Account_Control for more information). It does so by asking you to confirm when you are about to run certain programs.

When you start Defraggler, you may receive a UAC warning. Click Continue to use Defraggler.

I ran Defraggler and now I've lost one or more System Restore points:

This is a known issue with Windows and third-party defragmentation tools such as Defraggler. The problem occurs when the amount of disk space set aside for System Restore is too low.

Advanced users can clear out old System Restore points ('volume shadow copies') to make more room using this procedure.
