Windows 7: Programs not working after upgrade.

Hi guys,

Many programs that were installed are not working after upgrading to windows 7.

Namely Firefox, Thunderbird, Megaupload etc etc.
I tried re-installimg some of the programs, but nothing happens.

I also get this message on startup:

SetupDiEnumDeviceInterfaces() returns code: 259

Any ideas?

Should have done a fresh install.

To be honest I'm considering such a drastic action.

Never upgrade, always fresh install

Aye, fresh install! Upgrades are nothing but trouble.

I know its not relevant, but i suggest you wouldn't use that megauploadtoolbar. It fakes out pages errors such as 404, and while at it, it acesses GoogleAds for them to earn money.

And, as everyone said , do a fresh install

I successfully did an upgrade install (but not from Vista, although I have heard of many success stories upgrading to 7 from Vista). However, that said, a clean install is of course the best way to go, but 7 has improved the upgrade process considerably over the past versions of Windows, so if you have a lot of programs and settings, imo, it is worth giving an upgrade install a try. If it doesn't work out, no harm no foul, assuming one has made a good backup before starting on this. One can always do a clean install if the upgrade install doesn't work out satisfactorily.

Anyway, if you want to keep your programs and settings, you could give one more try at doing a "repair install." And if that doesn't work, then go ahead with the clean install (and consider using the Windows Easy Transfer utility to help with migrating data and program settings). If you want to try the repair install, specific instructions can be found in the tutorial section of this forum: Repair Install

Also, you can find instructions on how to use Win Easy Transfer in the tutorials.
