Java 1.8 not installing on Windows 7 error 1603?

Question

I am using Windows 7. My current java version is 1.6.0_05 (from cmd-> java -version)

I downloaded jre-8u25-windows-64 from the standard oracle site. When I run it, it says that java is used by the following program: ip2launcher.exe (I could not find out how to close this application)

When I click ok, it gives error 1603 that java cannot be installed.

I also tried to run jre1.8.0_25 (Windows Installer package) from C: \ Users \ admin \ AppData \ LocalLow \ Sun \ Java \ jre1.8.0_25_x64, but it gives an error that something is missing and java cannot be set.

Has anyone had this problem before ...? please help. I use an antivirus called YAC, can this be because of this?

Answer 1

Download and run the Microsoft installer and install the Fixit tool here: http://support.microsoft.com/mats/program_install_and_uninstall/en

After asking to select the program to uninstall, select the JDK / JRE that you are trying to reinstall. This will remove them. Then, once this is complete, you can proceed with the installation of the JDK / JRE.

Hope this helps!

Answer 2

SO I deleted YAC and yes .. he solved the problem .. he blocked some files, maybe .. :)
