Sometimes, when you try to uninstall any product in the Windows Programs and Features tool, a new Windows Installer window appears and gives the Windows 10 error opening installation log file.
It is accompanied by the message: verify that the specified location exists and is writable.
While it may not be obvious why the error appears, the issue usually occurs if the Windows Installer logging is enabled, but its engine can't write the uninstallation log file properly.
This happens if the Windows Installer's application heap is freed so it loses the information on where the log file should be stored.
When this happens, Windows Installer tries to write to the location C:\Windows\System32 and addresses it as a file.
The correct, or proper action should be to write it to the following location and file name: C:\Users<username>\Appdata\Local\Temp\MSIxxxxxx.log.
This problem can also occur if the Windows Installer files are damaged or missing.
Or when you install or remove a program that uses Windows Installer Microsoft Software Installation (MSI) package file (.msi), like if you try to install Microsoft Office on your computer.
It is a known issue with the Microsoft Installer engine, so there are ways of solving the problem, as outlined below.
