The installation or update method doesn't run to completion

Collapse this imageExpand this image
There are several methods that can be used to install, to uninstall, or to update a program. Additionally, the method or methods that are used may not have started or completed successfully. In this situation, try some other method to install, or to update the program.

The following are common methods that are used to install software:
  • Insert the CD or DVD media, and then let the installation auto-start.
  • Browse to the CD, DVD, removable media, or other location where the programs installation files are stored, and then double-click the Setup program. The setup file is typically one of the following:
    • Autorun or Autorun.exe
    • Setup or Setup.exe
    • Install or Install.exe
  • Click Run when you download the program from a website.

The installation media is unreadable

Collapse this imageExpand this image
Installation media such as CD and DVD media may be dirty or scratched and therefore be unreadable by the CD or DVD reader. To resolve this issue, follow these methods:
Method 1: Clean the CD or DVD
To do this, use a CD or DVD disc-cleaning kit. Or, use a soft, lint-free cotton cloth to gently wipe the silver side of the disc. Do not use paper cloth, as this can scratch the plastic or leave streaks. When you clean the disc, wipe from the center of the disc outward. Do not use a circular motion. If the problem continues to occur, clean the disc by using a damp cloth or a commercial CD or DVD disc-cleaning solution. Dry the disc thoroughly before you insert it into the drive.
Method 2: Copy the installation files to your computer or to other removable media
When you do this, note the location, and then run the installer from that location. The installation file is typically named Autorun.exe or Setup.exe, but this may vary. If you're not sure, check the Readme file in the folder for instructions about how to run the installation process. If an executable file (.exe) is available, we do not recommend that you run .msi files directly without specific instructions from the vendor.

Note If multiple CDs or DVDs are required, we recommend that you copy all the disks to the same folder, in reverse order (higher disk numbers first). Be prepared to approve the overwriting of existing files if you are prompted, and then install from that location.
Method 3: Obtain a fresh version of the installation package
If you tried to install from a CD or DVD, do the following:
  • Check the software manufacturer's website for a more recent version of the software package. Download and install the new version.
  • If you already have the latest version, download the program from the manufacturer's website, and then run the installation.

Downloaded or copied installation files are corrupted

Collapse this imageExpand this image
Method 1: Copy the installation files to your computer
Copy the installation files to a local hard disk on your computer or to other removable media. Note the location, and then run the installation from that location. The installation file is typically named Autorun.exe or Setup.exe, but this may vary. If you're not sure, check the Readme file in the folder for instructions about how to run the installation. If an executable file (.exe) is available, we do not recommend that you run .msi files directly without specific instructions from the vendor.
  • If you are installing a program from the Internet, redownload the file (select Save instead of Run in the download dialog box), save the file to a folder on a local hard disk on your computer or to other removable media. Then, run the installation from that location.
  • If your installation files are on a network (for example, a commercial or corporate environment), copy all the files to a folder on a local hard disk on your computer, and then run the installation from that location.
Method 2: Obtain a fresh version of the installation package
If some time has elapsed between when you downloaded the package and when you tried to install it, do the following:
  • Check the software manufacturer's website for a more recent version of the software package. Download and install the new version.
  • If you already have the latest version, download the program again, and then run the installation.

Advanced troubleshooting steps

Note The following steps are appropriate for advanced users only.

Check for overly long file and folder names

Collapse this imageExpand this image
Make sure that you don't have any file or folder names that are longer than 260 characters.

For more about the maximum path length limitation, see Naming files, paths, and namespaces (http://msdn.microsoft.com/en-us/library/aa365247.aspx#maxpath) .

Enable MSI logging, and then read the .msi verbose log files

Collapse this imageExpand this image
Most programs create an installation log. If you can't locate such a log, you can enable verbose MSI logging. For more information, see How to enable Windows Installer logging (http://support.microsoft.com/kb/223300) .

Note If you're running the .msi log file without the bootstrapping application (.exe), you can add parameters for verbose logging. For example, you can run the following command:
Msiexec path\your_msi.msi /L*v path\your_msi_log.txt
For a list of msiexec command-line parameters, see Command-line options (http://msdn.microsoft.com/en-us/library/aa367988%28VS.85%29.aspx) .

A failed installation typically logs "Return Value 3" where the problem occurred and where the installation rollback began. The description of the failure appears immediately before the Return Value 3 log entry.

Use Wilogutl.exe to analyze log files

Collapse this imageExpand this image
You can use the Wilogutl.exe (http://msdn.microsoft.com/en-us/library/aa372811(VS.85).aspx) tool to analyze log files from a Windows Installer installation. This tool may suggest solutions to errors that are found in a log file. It is available in the latest Windows Software Development Kit (http://msdn.microsoft.com/en-us/windows/bb980924.aspx) .

The following is an example of how to use the Wilogutl.exe tool at a command line:
wilogutl /q /l c:\mymsilog.log /o c\outputdir\

Manually uninstall the program

Collapse this imageExpand this image
You may be able to manually uninstall some parts of the program through the Windows interface. For example, you may be able to delete program files and folders. Because the steps to do this may differ widely, depending on the version of Windows that you're running and on the program that you're trying to uninstall, no prescriptive steps are provided here. If you're not sufficiently familiar with the program that you're trying to uninstall to positively identify the files and folders for that program, we do not recommend that you try this method. Generally, when you begin to delete program files and folders, you run the risk of damaging your operating system. Use this method at your own risk.

If you are considering uninstalling the program manually, be aware of the following:
  • Before you use this method, make sure that you create a system restore point.
  • Before you get started, move any personal data or documents that may have ended up in the installation folder of the program that you’re uninstalling. For example, move this material into the Documents folder.
  • If you cannot manually delete a program file, this may mean that the file is being used or that some other program is accessing the file and preventing you from deleting it. For example, antivirus software may be accessing the file. When antivirus software is accessing a program file and making it impossible to delete it, it's likely that this same antivirus software was preventing you from uninstalling the program by more traditional means.
