Disabled Short Filename (8.3) support will cause Backup Exec 11d install to fail on installing MSXML.


V-225-235: MSXML 4.0 failed to install


During the Backup Exec 11d installation a dialog box will appear for the Windows Installer (Figure 1)

Figure 1 Windows Installer switches

Selecting OK results in the installation failing with "V-225-235: MSXML 4.0 failed to install" and "V-225-235: MSXML 4.0 SP2 failed to install" reported in the installation log (bkupinst.htm). The installation log will also report "Short file names are not enabled. This may cause the Backup Exec installation to fail."

This will happen if an attempt is made to install Backup Exec 11d to a server where short file name support is not enabled within the operating system.  If short file name support is re-enabled and a second attempt is made to install Backup Exec 11d, then the installation will still fail with "V-225-235: MSXML 4.0 failed to install", but the message regarding short file names not being enabled will not be present.


Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

1. From the Start menu, select Run, enter REGEDIT and click OK.
2. Expand HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
3. Right-click NtfsDisable8dot3NameCreation select Modify.
4. Set the Value data for NtfsDisable8dot3NameCreation to 0 and click OK.
5. Close REGEDIT.
6. Reboot the server.
7. Use Windows Explorer to locate the %ALLUSERSPROFILE%\Application Data\Symantec folder. (Figure 2)
Note: this folder may be hidden and is usually located in C:\Documents and Settings\All Users\Application Data\Symantec

8. Delete the Backup Exec folder and the backup file. (Figure 2)
9. Re-run the Backup Exec 11D installation.
