I had a similar problem. I had installed JDK7 update 1 but couldn't use it (probably because I found a JRE6 that I deleted after installing JDK7). Uninstalling JDK7 was impossible. The solution was to add the JRE registry entries by hand.

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java RuntimeEnvironment]"CurrentVersion"="1.7"[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java RuntimeEnvironment\1.7]"JavaHome"="C:\\Program Files\\Java\\jre7""RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java RuntimeEnvironment\1.7.0_01]"JavaHome"="C:\\Program Files\\Java\\jre7""RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

You'll have to adjust the above to your own directories and version.

Make sure you remove any java.exe, javaw.exe and javaws.exe from your Windows\System32 folder and if you have an x64 system (Win 7 64 bits) also do the same under Windows\SysWOW64.
