SYMPTOMS
If you try to install an Office 2000 program on a Microsoft Windows 2000-based computer, you may receive the following error message:

Windows File Protection:

Windows files must be installed for your installation to proceed.

When you click OK, another dialog box appears that gives you these options: Retry, More Information, or Cancel. You are not given the option to locate the Windows files.



CAUSE
This problem occurs if either of the following conditions is true:
 * The Setup path in the registry points to an incorrect location for the I386 folder. The Office 2000 products update system files and Windows File Protection need access to the I386 folder to verify the integrity of the certain files.
 * The number of files cached by Windows File Protection is too low.



RESOLUTION
To resolve this issue, use either of the following methods.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Method 1: Change the Registry SourcePath Value
 Click Start, and then click Run. In the Open box, type regedit, and then click OK. Locate and then click the following key:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Setup

 In the right pane, double-click SourcePath. In the Edit String dialog box, specify the location of the I386 folder.

NOTE: Because you have this folder on your hard disk, you can point to that location. For example, if path is C:\Windows\Driver Cache\I386, give this key a value of C:\Windows\Driver Cache. Quit Registry Editor.</li></ol>

NOTE: You may have to repeat these steps for the ServicePackSourcePath key.

Method 2: Increase the Number of Files Cached by Windows File Protection
<ol> Click Start, and then click Run.</li> In the Open box, type regedit, and then click OK.</li> Locate and then click the following key:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Winlogon

</li> In the right pane, double-click SfcQuota.</li> In the Edit DWORD Value dialog box, under Value data type ffffffff, and then click OK.

NOTE: The value includes eight f's. The value should read 0xffffffff (4294967295). This specifies the size of the cache, as does the command line.</li> Quit Registry Editor.</li> Click Start, and then click Run.</li> In the Open box, type command, and then click OK.</li> At the command prompt, type sfc /cachesize=ffffffff /scanonce, and then press ENTER.

NOTE: The command includes eight f's.</li> Type exit, and then press ENTER.</li> Restart your computer.</li> Install Office 2000.</li></ol>
