The Temp Directory Contains a Large Number of Files

The Temp folder may contain files that are interfering with the installation of Office. To remove these files, use the appropriate method for your operating system.

Microsoft Windows NT 4.0 or Microsoft Windows 2000

In Microsoft Windows NT 4.0, navigate to the Temp folder, which is usually located in the root folder of the system hard disk (C:\Temp). Display the contents of the Temp folder with details, and delete files that were not created on the current date.

Microsoft Windows 95 or Microsoft Windows 98

  1. Restart your computer. Press F8 when you see the "Starting Windows 95" message, and then choose "Safe mode command prompt only."

    In Windows 98, hold down CTRL until the Microsoft Windows 98 Startup Menu appears and choose "Safe mode command prompt only.". On some computers, you can press F8 instead of CTRL to bring up the Microsoft Windows 98 Startup Menu.
  2. Type set and press ENTER. Note the location of the TEMP variable.
  3. Go to the folder noted in step 2. For example, if TEMP is set to C:\WINDOWS\TEMP, type the following line and then press ENTER:
    If the folder noted in step 2 does not exist, you must create the folder. For example, you can create a temporary folder called win95tmp on your hard disk by typing the following line at the command prompt:
    md c:\win95tmp
  4. Delete any temporary files in this folder. Temporary files typically have a .tmp extension. To delete these files, type the following line and then press ENTER:
    del *.tmp
    NOTE: Do not delete these files from within the Windows 95 graphical user interface (that is, when you are running Windows 95) because Windows 95 or a Windows program may be using one of these files.

Microsoft Windows Millennium Edition (Me)

  1. Click Start, point to Programs, point to Accessories, point to System Tools, and then click System Information.
  2. On Tools menu, click System Configuration Utility.
  3. Click the Environment tab and look for the TEMP variable. If the TEMP variable is missing, click New and type TEMP for Variable Name, and C:\Windows\Temp for Variable Value. Click OK.
  4. Click OK, and then click No if you are prompted to restart your computer.
  5. Insert your Windows Me startup disk in your disk drive.
  6. Click Start, and then click Shut Down. Make sure Restart is selected is the drop-down list. Click OK.
  7. After you restart Windows to a command prompt, type the following, and press ENTER after each line:
    If the cd\windows\temp folder does not exist, you must create the folder. You can create the temporary folder on your hard disk by typing the following line at the command prompt:
    md c:\windows\temp
  8. Delete any temporary files in this folder. Temporary files typically have a .tmp extension. To delete these files, type the following line and then press ENTER:
    del *.tmp
