The wizard was interrupted before Java could be completely installed

Thursday, October 25, 2012

"The wizard was interrupted before Java 7 Update 9 could be completely installed. To complete installation at another time, please run setup again."

If you understand a little bit how registry works you can try out to remove java root keys in registry. I have automated this java root key remove process in Java Destroy post.

If you do not like playing with registry at all, then just download and install Total Uninstall.

Total Uninstall works similar like add/remove programs. Let's take a closer look.
Open Total Uninstall. Look for java and click Uninstall button.

Select "Uninstall analyzed program" and pres "Launch"

You can skip this part:

Are you sure you want to uninstall this product?
This part will use original uninstaller.If you try it already, click "No":

The final dialog came out. Click "Uninstall".
This will delete all java registry keys

And finally - Finisho!

Repeat this steps for all installed java versions. In another words - it is a huge possibility when you uninstall one of version then the other ones is already damaged. You have to get all java versions away from computer. If java is removed, it will apears in color gray:
Now you can visit java download page to install brand new java.

Be happy.


  1. Excellent suggestion. Thanks! The Java uninstaller was failing, as was JavaRa (a specialized Java uninstaller). Total Uninstall actually got rid of it, fixing both the uninstall and the reinstall problems I was having.

    I used Total Uninstall and it removed old java very good, so i could finally instal succesfully new Java!

  7. Yes, yes, yes!!! Took me 4 hours of manually sorting and searching in registry, fghting this stupid thing. Then I found this and everything works in 30 seconds. God bless you!

  8. Dear Sir..

    Who ever posted the Total Uninstall tool BIG BIG BIG Thank you..
    Great support, great help and finally a real brilliant tool.

    Not only did it solve Java New Installation / Update problem, but It also solved a long lasting problem installing any Kaspersky or Avast softwares on my PC. After uninstalling old softwares using Total Uninstall tool, I was able to re-install the new updates safely without usual intterupting pop-up Error msgs and codes.

    Keep up the goog spirit.
