If they are, see your product documentation to complete these steps.
This article contains information about troubleshooting and eliminating invalid page faults that occur in module Kernel32.dll when you work with a Microsoft Office program under Microsoft Windows 95. When a Kernel32.dll error message appears, a message similar to the following appears:
where Program name is the name of the program you are using.
Program name caused an invalid page fault in module Kernel32.dll
When an invalid page fault occurs, an unexpected event occurs in Windows. An invalid page fault typically indicates that a program incorrectly attempted to use random access memory (RAM); for example, when a program or a Windows component reads or writes to a memory location that is not allocated to it. When this occurs, the program can potentially overwrite and damage other program code in that area of memory.
An invalid page fault may occur when parameters are passed between programs and Windows. An invalid parameter may cause a program to run invalid instructions, which results in an invalid page fault. This behavior usually occurs because a program incorrectly passes data that Windows or a Windows-based program cannot interpret.
It is important that you follow the steps in each of the sections in this article in the order in which they are presented. Because invalid page faults are typically caused when two or more programs interact, skipping steps may prolong identifying the problem.
Determine whether the problem is documentedMany Kernel32.dll errors are documented in the Microsoft Knowledge Base and have solutions. For more information, browse to the following Microsoft Knowledge Base Web site:

Start Windows in Safe ModeWindows has a built-in troubleshooting mode called Safe mode. It bypasses startup files and uses only basic system drivers, including basic networking. When you start Windows in Safe mode, Windows uses only the mouse, keyboard, and standard video graphics adapter (VGA) device drivers. This makes Safe mode useful for isolating and resolving error conditions that are caused by both real-mode and Windows-based drivers. Windows also has troubleshooting features that may help you identify the problem. To start Windows in Safe mode and make the additional troubleshooting features available, follow these steps:

Turn off the CD-ROM drive cacheIf the error message appears while you are reading from a CD-ROM drive, try turning off the CD-ROM drive cache. This may make the drive more reliable but reduce performance. To turn off the CD-ROM drive cache, follow these steps:
Check for registry damageWarning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
When you start Windows in Safe mode, Windows does not read the entire registry. Therefore, damage to the registry may not be evident when you run Windows in this mode. It may be necessary to replace the existing registry (System.dat) with a backup to determine whether the problem is caused by a damaged registry. To troubleshoot a damaged registry, follow these steps:
If replacing the System.dat file with the System.1st file resolves the issue, the problem may be related to registry damage. Note that you may have to reinstall programs and device drivers that you installed after you installed Windows to update the new registry.
If the issue is not resolved, restore the original registry. To do this, follow these steps:

Check for a valid temporary folder and delete temporary filesThere should be at least 20 megabytes (MB) of free space on the hard disk that contains the temporary folder. To check for a temporary folder and delete excess files from that folder, follow these steps:
Check the hard disk for disk errors and fragmentationUse the ScanDisk program to check the hard disk for lost clusters and other file allocation table (FAT) errors and to test the hard disk integrity. You can also use the ScanDisk program to repair any of these problems. To run ScanDisk, follow these steps:
Verify that the compact disc is clean and unscratchedIf the error message appears while you are installing from a compact disc, verify that the compact disc you are using is clean by wiping the compact disc with a soft, lint-free cloth. Also ensure that there are no large scratches on the compact disc. If the compact disc is damaged and unreadable, error messages may appear during installation.
Check for a damaged swap fileThe Kernel32.dll error may also appear if your Windows swap file is damaged. To create a new swap file, restart the computer in MS-DOS mode, delete the Win386.swp file in the Windows folder, and then restart the computer. To create a new swap file, follow these steps:
Damaged custom profileDamaged custom profiles are also known to cause Kernel32.dll errors. Deleting and recreating the profile can possibly resolve this problem.
If you are using the Office system policy templates that are included in the Microsoft Office 2000 Resource Kit, you must use the version of the System Policy Editor that is included in the Microsoft Office 2000 Resource Kit.
Note The System Policy Editor that comes with Windows 95 does not work with Office 2000. Be sure to install the latest version of the System Policy Editor from the Microsoft Office 2000 Resource Kit or from Windows NT Server 4.0 with Service Pack 4. You can download Policy.exe, a self-extracting file containing Poledit.exe, from online services. Download this file from the following Web site:
Turn off enhanced BIOS featuresMost computers have several enhanced settings that allow the computer to fully use the computer hardware. These high-speed settings can cause the system to become unstable; turning off these features may make the computer more stable. Contact your computer manufacturer for information about entering the basic input/output system (BIOS) and changing the BIOS settings. You can enter the BIOS on most systems immediately after turning on the power. Usually a keystroke (such as DEL) is required to enter the BIOS. Below are the common features that can interfere with Microsoft Office programs:
Warning Incorrectly altering hardware BIOS settings can cause serious problems that may cause your computer to fail to start or function properly. Microsoft cannot guarantee that problems that result from the incorrect setting of hardware BIOS options can be solved. Alter the hardware BIOS settings at your own risk.
Customers have reported that the Dell A02 BIOS does not work with Windows This BIOS version is used on the Dell Dimension models. Dell technical support can be contacted at (800) 624-9896.
Disabling the External Cache feature on Tyan Titan III VX and Tyan Tomcat III motherboards has been known to resolve Kernel32.dll error messages. Similar problems have also been reported when using Gigabyte motherboards.
Remove and reinstall the programIf the problem occurs after you run the Setup program, some of the dynamic link library (.dll) files may be damaged or corrupted. To troubleshoot this problem, first completely remove the program. After you completely remove the program, reinstall the program.
Check for software updatesOutdated and incompatible software may also cause error messages to appear. Check with the manufacturer of the computer for various software updates, such as BIOS updates, OEM Windows updates, and hardware driver updates (such as CD-ROM drive drivers). If you are using third-party partitioning software (for example, EZDrive, or Ontrack Disk Manager), verify that you have the most recent versions of these products.
Microsoft has released three updated files that may affect whether you receive error messages when you run Setup or when you use an Office program. Download the Windows 95 Service Pack 1, the Kernel32.dll update, and the Ole32.dll updates from the Microsoft Web Site. Also, determine whether other updates that may pertain to your system configuration are available. To check for updated files on the Microsoft Web site, use the following address:
Scan the computer for virusesIf a virus is present on your computer and has damaged some files, Kernel32.dll error messages may appear when you use a program. Scan the hard disk and floppy disks with a virus detector. If the virus detector finds a virus on your computer, remove the virus before you run the Office program again.
Note Do not run a virus detector terminate-and-stay-resident (TSR) program while you run any of the Office programs, including the Setup program. Run a virus detector before you run the Setup program, and then disable it.
