I have been unsuccessful getting a Java WebStart application that should have AllPermissions to write a file to Windows/System32 on Vista or Windows 7. While I don’t believe this is possible, perhaps there is a way to lower the integrity level of this folder to Medium?

I am getting desperate and am not above insane registry hacks to make this happen. We have a production app that runs fine on Windows XP however a new prospective client is unbending in their determination to ONLY maintain Windows 7 or Vista workstations.

I appreciate any help or suggestions and would especially love to hear from anybody if this is impossible. Please no comments on how insecure and dangerous this can be, I am aware of the risks.

    The proper solution is to have the required DLLs placed in the system32 folder from your installer.

    Your MSI installer will know how to prompt the user to elevate to administrator, so you then have permission to add your files to the users System32 folder.

    You will not be able to modify files in the users’s System32 without them being (or elevating to) an administrator; that’s a fundamental constraint of the secure operating system.
