Having trouble uninstalling or fixing Java from a Windows 7 machine like I did? I somehow managed to mess up my Java installation and was receiving an error 1723 along the way while trying to uninstall the 64-bit version of Java 6 (in my case version 6.0.31). It was complaining about not being able to find a certain file which it apparently needed for the uninstall. What I did was the following:
Step 1:
Locate the following folder:
C:\Users\<User>\AppData\LocalLow\Sun\Java\jdk1.7.0_x64
and make a copy of it in
C:\Users\<User>\AppData\LocalLow\Sun\Java
If it isn't there, you need to downlaod and install Java jdk1.7.0_x64.
Step 2: Rename the copied folder to
C:\Users\<User>\AppData\LocalLow\Sun\Java\jdk1.6.0_31_64
Step 3:
Rename
C:\Users\<User>\AppData\LocalLow\Sun\Java\jdk1.6.0_31_64\jdk1.7.0.msi
to
C:\Users\<User>\AppData\LocalLow\Sun\Java\jdk1.6.0_31_64\jdk1.6.0_31.msi
Following those steps combined with some restarting of Windows allowed me to Uninstall my corrupt Java 6 version. Make sure you replace <User> above with your Windows user name. I hope that helps someone!
