8.8.2 product version update fails on 64bit Windows 7

[marine2026]

When installing onto a 64bit Windows 7 OS, the installer fails to correctly update/replace the previous installation.

I am updating the Product Version.
Files and Folders is set to install into the Parent Directory, and to Insure that all files in this folder overwrite any installed target files.

I've tried creating an installer all-in-one in the exe, and separately (exe, msi, cab). Both correctly work on non-64bit Windows 7. Neither work, update the files on 64bit Windows 7.

Please help!
Thanks!!

Can you please send us a verbose log created on the x64 machine, along with the aip file to support at advancedinstaller dot com, so we can investigate this further more?
