Disk Utility Could Not Validate Source


Other Resources:
There are other reasons the QuarkXPress installer application can fail under Windows XP. These are listed along with suggested solutions below:



  1. The DCOM default impersonation level is set to Anonymous.

    • The SYSTEM account does not have Full permissions on a folder that the Windows Installer is trying to access.
      Note: This behavior is specific to the NTFS file system.


      • The windows installer version 1.x data information is not migrated to the windows installer version 2.x that SP3 installs on the computer. The windows installer does not see that Office is installed on the computer because SP3 updated your windows installer from 1.x to 2.x. Therefore SP3 moved all your windows installer data files, which include Office products from the 1.x windows installer registry keys to Windows installer 2.0.
        Note: This behavior is specific to the NTFS file system.


        • Version 2 of the Windows Installer that is included with SP3 for Windows 2000 does not work if the DCOM default impersonation level is set to Anonymous.








Solutions for these alternate causes:
Use the following methods in the order they are presented until the issue is resolved.
Method One:
Change DCOM Impersonation Level to Identify,remove the Msisip.dll file, and then reinstall SP3 for Windows 2000. To do this, follow these steps:



  1. Click Start, click Run, type dcomcnfg, and then click OK.

    • Click the DefaultProperties tab.

      • In the Default Authentication Level list, click Connect.

        • In the Default Impersonation Level list, click Identify, and then click OK.

          • Click Start, click Run, type explorer /select, %windir%system32msisip.dll, and then click OK.

            • Rename the Msisip.dll file to 'Msisip.old'.

              • Install the latest MSI 2.0 redistributable package. To do so, visit the following Microsoft Web site:
                http://www.microsoft.com/downloads/release.asp?ReleaseID=32832


                • Restart the computer.

                  • Reinstall SP3 if it is not already installed. (You can use winver.exe to see whether SP3 is already installed.)


















Method Two:
Grant Full Control Permission to the SYSTEM Account:



  1. Start Windows Explorer, right-click the computer's root hard disk, and then click Properties.

    • Click the Security tab, and then click Add.

      • In the SelectUsers, Computers, or Groups dialog box, click the SYSTEM account, click Add, and then click OK.

        • Click to select the FullControl check box under Allow, and then click OK.








Method Three:
Apply the MSI Registry Hotfix available from Microsoft, Msiregmv.exe. This hotfix moves all the windows installer 1.x data registry keys to the Windows installer 2.x registry data location.
