I have downloaded the setup software several times but I cannot get any of it to load. I get the message that it is not a valid Win 32 application. I am running Windows 7. I have no problems with Thunderbird on other machines. There are no help paragraphs anywhere in your system that address this issue - at least not using the available public index.

if the installer is not valid, it will be because it has been corrupted in the download process. Usually by an over helpful anti virus program. As the installer is basically a 7Zip executable some corporate system will not allow the executable to run as it contains a ZIP file.
