All Palo Alto Software products come with an updated, fully licensed, version of the Xceed Zip compression library, XceedZip.dll. The message which you are encountering indicates that the XceedZip.dll file has been overwritten by an older, unlicensed version.

Take the following steps to replace the current version of XceedZip.dll on your computer with the updated version which is licensed for distribution with our software:

1. Close any open programs and restart the computer to ensure that this file is no longer flagged as "in use" by Windows.
2. Download the updated version of the file:
   1. Click the link below to begin downloading the file from our FTP server:
      XceedZip.dll
   2. When prompted, choose to Save this file to the appropriate directory on the hard drive of your computer:
      Windows XP: C:\Windows\System32
      Windows 2000: C:\WINNT\System32
      Windows 98 or ME: C:\Windows\System
   3. If Windows states that the file already exists, choose to over-write the older version of the file which is already in this location.
3. Once the file has been saved, take the following steps to register the new version of the file with the Windows XP operating system:
   1. Click on Start and then Run.
   2. Type the appropriate command for your version of Windows into the Open box and click OK:
      Windows XP:
      REGSVR32 "C:\Windows\System32\XceedZip.dll"
      Windows 2000:
      REGSVR32 "C:\WINNT\System32\XceedZip.dll"
      Windows 98 or ME:
      REGSVR32 "C:\Windows\System\XceedZip.dll"
   3. Windows will display a message that the Dllregistryserver in the file succeeded. Click OK to this message.
4. You should now be able to launch the Business Plan Pro software without encountering the message about the older version of XceedZip.dll.
