No, the application will not work on 64bit operating systems. Although it was developed some time ago, it still works with newer operating systems like Windows 7 and Windows 8 but on 32bit mode only. However, to install it in Windows 7 or 8, Net Framework 1.1 needs to be wiped off the system or you'll encounter errors. You can do this using the following cleanup method:
cleanup_tool.exe /q:a /c:”cleanup.exe /p .NET Framework 1.1
You can download the CleanUp Tool through Google Search.
