When attempting to upgrade Confluence using Confluence Windows Installer, you might get the warning that some Confluence install files are locked by another process and the upgrade cannot proceed.

If you ignore that message, Confluence will not be upgraded properly and you will encounter errors and your instance might not start.

You should NOT ignore that message.

Diagnostic Steps

Use Process Explorer Tool to find out which process is locking the file/folder.


A Windows executable called conime.exe is the console input method editor associated procedures, allows the user to use the standard keyboard to enter the complex characters and symbols. conime.exe is a Windows system file. conime.exe locks some files in Confluence install directory and does not allow Confluence installer to upgrade those files.


Kill conime.exe from either Windows Task Manager or from Process Explorer Tool and run Confluence windows installer again. 

The installer should be able to upgrade Confluence install files.
