a.) A quick visit to Google tells me you have a difficult problem if you are getting this error message 0X643. A quick overview suggests you will need some technical savvy to get your way through it. If practical, you might want to try reinstalling Windows at this point. The way I avoid this type of problem is to just allow Windows Update to perform whatever update it wants to, whenever it wants to. Maybe Geeks on Call (or someone else on this list) can help. On the other hand, if you are not experiencing other symptoms than this Windows Update error, then you could just ignore it for the time being. b.) I don't know how to tell whether any given program requires .NET. I determined (again via Google) that Office 2007 requires .NET v1.1. It is mostly a programmer's concern. For a long time, the programming tool of choice for Windows was Visual Basic. I suspect a lot of software being sold is still written in that, which will run just fine. The .NET equivalent of this is VB.NET, plus a brand new language known as C# was introduced at the same time, which grew rapidly in popularity. But if you're not a programmer, you could care less. Unfortunately, both "traditional" Visual Basic and "new fangled" VB.NET and C# compilers create files with either the extension ".exe" or ".dll". I don't know how to tell from looking at these how the programs were written.
A lot of software running on Windows is cross-platform, in which case it may have been written in C++ and compiled on Windows using Visual C++. There is also some stuff written in Java (I am a Java programmer). The Java programs are easiest to identify, but tend to be used by people having specialized interests. Hope this helps somewhat! --John Emmerling On Mon, Dec 21, 2009 at 10:29 AM, Clair Esch <[email protected]>wrote: > What are some examples of something running that needs .net?
