Why Error 0x80070643 – Fatal Error During Installation Reported

Error 0x80070643 is a generic error message and finding the root cause of the issue is not straightforward. You may receive this error message under the below conditions:

  • The folder that you are trying to install the Windows Installer package to is encrypted.
  • The drive that contains the folder that you are trying to install the Windows Installer package to is accessed as a substitute drive.
  • The drive that contains the folder that you are trying to install the Windows Installer package to is a CD / DVD drive.
  • Windows Installer is attempting to install an app that is already installed on your PC.
  • The SYSTEM account does not have Full Control permissions on the folder that you are trying to install the Windows Installer package to. You notice the error message because the Windows Installer service uses the SYSTEM account to install software.
  • Unknown Cause: The Verbose logging can be used to capture detailed logs during installation. Reviewing these logs provides more information on why the installation was failed.


To resolve the issue, you need to do any of the following depending on the cause of the problem:

  • Install the package to a drive that is not a CD/DVD drive or not accessed as a substitute drive.
  • Install the package to a folder that is not encrypted.
  • Check if the app is already installed on the PC. If so, uninstall and reinstall the app.
  • Grant full control permission to the SYSTEM account on the target folder where you are trying to install the application.
  • Generate a verbose log to identify the possible issues. Continue below to learn about verbose logging.

Verbose Logging

Microsoft installer handles the installation through MSIExec.exe. The logging option offered by this tool allows you to capture detailed information about installation in a log file. The most used logging command line option is /L*V.

Here is a complete MSI command line. This command will create a log file App1.log in the provided path and capture detailed information about the installation in the logs. You can analyze the log file in the notepad or CMtrace to identify failure reasons.

msiexec /i <MSI PATH> /L*V <LOG FILE>

msiexec /i “C:\Temp\App1.msi” /L*V “C:\log\App1.log”

The Winzip installation was failed with error 0x80070643. The below command line was used.

msiexec /i winzip260-64.msi /qn INSTALLDIR="D:\Program Files\WinZip26" ALLUSERS=1

By looking into IntuneManagementExtension.log , you can understand that the command line is trying to install the application in D: drive and then failed with1603 error.
