You can encounter this error if TMP and TEMP directories are different. This can result in installer files being written to TMP but when attempting to read those files using the TEMP value you see in the error.
Confirm that both values are referring to the same path. For example, from a command prompt:
and then run the installation again
Otherwise, it looks like an operating system permission issue.
This can occur if Windows Installer Logging is enabled, but the Windows Installer engine cannot properly write the uninstallation log file. This condition can occur if the Windows Installer's application heap becomes freed and thus loses the information on where to store the log file. When this occurs, Windows Installer attempts to write to the location 'C:\Windows\System32' and addresses it as a file. Proper behavior would be to write to the following location and file name: 'C:\Users\<username>\AppData\Local\Temp\MSIxxxxxx.log'.
What causes ‘Error opening installation log file’?
As discussed above, this error is related to logging of Windows Installer. Logging is basically keeping track of all the installs and uninstalls and storing them. This way you can get the technical details in a text document. A detailed list of why this error might occur is:
The Windows Installer module is having trouble keeping a log of installs and uninstalls because it doesn’t know where to store the file.
The Installer is either corrupt or its installation file are missing.
Windows Explorer is directly related in all of Windows Installer workings. It may be in an error state.
Before you move on with the solutions, make sure that you have administrator privileges. We might be executing some command prompt statements which may need elevated status.
1: Running the application’s uninstaller
Before you move on to the detailed solutions, it should be noted that it is always recommended to uninstall a program using its own uninstaller. When you uninstall a program using the Windows Application manager, it might not always launch the application’s native uninstaller application. When you use the application’s native uninstaller, it bypasses all these issues which Windows Installer encounters and uninstalls the program properly after removing all the files. You can find the application’s uninstaller by navigating to its directory and locate the file ‘uninstall.exe’. Run it and follow the on-screen instructions. Make sure that you have administrator access.
