If both Microsoft and Panasonic state there are no updates available for Windows 7, it looks like the software is not compatible with Windows 7.
Which Windows 7 version did you upgrade to? If you have either the Professional or Ultimate edition, then you could try 7's XP Compatibility Mode;

Also available with those Windows 7 versions is Virtual PC where you could install XP as a virtual OS, and run the software from there;

Other than that, I fear you are looking at replacing the software.

Have recently updated computer from Vista to Windows 7 but now unable to operate PhotofunStudio 1.4 the operating software for the Panasonic Lumix DMC-FZ18 digital DSLR camera, which workrd perfectly under both Vista and XP. Both Microsoft and Panasonic have confirmed that no update has been issued to work with Windoes7. As this camera is perhaps the best that Panasonic have ever made, used daily for yacht surveying, with over 200,000 photos to date, I am loathed to change it for the sake of a good new driver. I have used Picasa 3 as a replacemen, but it does not give me the versatility I used to get from PhotofunStudio. I know there are many others experiencing the same problem. Any ideas
