Can't install JDK 9 because “Another Java installation is in progress”

Question

I have been using JDK 9 on Windows 10 x64 for a while but when I went to install the latest early release (b174), I first uninstalled the previous version (as usual) and then ra

Answer 1

On Windows, Java prevents starting the Installer twice by creating (two) lock files. If those files exist, Java Installer show the Message: "Another Java installation is in progress (...)".

If Java Installer crashes, or Windows crashes during Java Installation, the installer cannot delete the lock files when finalizing.

Solution:

Deleting the lock files, unlocks the Installer and Java can be installed again.

The lock files are located at:

C:\ProgramData\Oracle\Java\JAVA_INSTALL_FLAG
%USERPROFILE%\AppData\LocalLow\Sun\Java\JAVA_INSTALL_FLAG
%USERPROFILE%\AppData\LocalLow\Oracle\Java\JAVA_INSTALL_FLAG

Answer 2

Although this was written for JDK9, JDK10 will suffer from the same issue BUT the lock location is different. The new lock file is located in %USERPROFILE%\AppData\LocalLow\Sun\Java\JAVA_INSTALL_FLAG.

Simply deleting this file should allow you to proceed with the install.

Answer 3

on windows 10, delete below directories,

C:\Program Files\Java C:\ProgramData\Oracle\Java C:\Users\%UserName%\AppData\LocalLow\Sun\Java C:\Users\%UserName%\AppData\LocalLow\Oracle\Java

and try again.

Answer 4

Kill any remaining Windows® installer msiexec.exe processes using the Task Manager of Windows. The Windows installer process apparently locks any java files/processes which blocks the Java JDK to be updated.

My problem installing Java 9 began after I upgraded JetBeans IntelliJ which uses Java JRE/JDK. I first tried the suggested solution that BlackSheeep posted, but without any luck.

Answer 5

I had this problem also and i came to this page but i couldn't solve it at first because i thought my system didn't have 'ProgramData' in my C: drive because its hidden i guess. This is what worked for me. Go to the windows file explorer and delete the 'JAVA_INSTALL_FLAG' files in all these directories

%ProgramData%\Oracle\Java
%UserProile%\AppData\LocalLow\Sun\Java
%UserProile%\AppData\LocalLow\Oracle\Java

Then Java jdk installs smoothly. i have recreated this problem and tried this solution again and it works.
