Javaws 64-bit fails to installer newer JRE (Java7u6 auto-upgrading to u7)

Question

Hi,
I have a machine with an previous version of java installed (tried with 1.7.0_06).
My Jnlp file is set to automatically download the latest JRE. This works fine if the JRE installed is 32-bit. But if the user has downloaded the x64 bit version (on windows 7), everything works, except when I change the required version spec to 1.7.0_07.
The confirmation dialog to install 1.7.0_07 comes up but fails, as it tries to download and run the 32-bit installer while the javaws is 64-bit. Shouldn't the 64-bit version download a 64-bit version when auto-downloading?
The user is running javaws from the commandline
javaws.exe http://myserver/myapp.jnlp
h3. This is the jnlp file generated by javaws to auto download the JRE

Hi outpaddling,
Remember, you tried the "cacls" command and it did not work for you. I spent sometime on it and found that on Win7, there's command called "takeown" on Win7, which allows an administrator to recover access to a file/folder that was denied by re-assigning file ownership.
Could you try the following?
Note: You must elevate the level of permissions for Win 7 with UAC enabled.
On Windows 7
Choose Start > Programs > Accessories.
Right-click on Command Line and select Run As Administrator.
If Error 1321 is being caused due to some file e.g. if it's ACE.dll, then it's containing folder e.g. "C:\Program Files (x86)\Adobe\Reader 9.0" is to be mentioned in the below command line. The below command in blue can be typed at the command line and the end press Enter Key.
C:\Windows\system32>takeown /f "C:\Program Files (x86)\Adobe\Reader 9.0" /r /d y && icacls "C:\Program Files (x86)\Adobe\Reader 9.0" /grant administrators:F SYSTEM:F /t
After running the command, you should be seeing something like this,
Successfully processed 1367 files; Failed processing 0 files
And then try installing Reader 9.3.3 from http://ardownload.adobe.com/pub/adobe/reader/win/9.x/9.3.3/enu/AdbeRdr933_en_US.exe
Hope, it helps.
