Plainpc, On their page under system requirements it has a link for the .NET framwork

Plainpc,
It looks like there was an error on today's download page stating that it could run on XP, if you look at download the link sent by Randy Burrell in reply to you system specifications is a minimum of Vista.
The net framework required will not install in XP.

Jeff, Thanks for that tip!

Terry Chaney, I agree, not every program that GOTD offers is of use to me, but like you I have found plenty that I love. I have been here for years, not only because of the software offers, but also for the comments of other computer users.

suntsu33,
"The Freeware provides the opportunity to handle 10.000 Data Sets." It's not 10,000 Data Sets, but 10,000 records. That's not much. Just enough to test drive the product, I suspect.

Also, the video tutorial available at their site does not run on my machine. It tells me that the MIME format used is not supported on my machine.

SkippyK, Thank you for the hint. The tutorial runs fine on my win7 ultimate machine.

Seb, XP SP3 has been discontinued for a reason - it has many security holes now and vulnerabilities. It is an unsafe operating system. Windows 7 would be better, preferably Windows 8.1. There is no valid reason to stick to XP anymore. It is like saying Go Karts are the best means of transport, rather than use a car with proper brakes, windscreen and protection.

Chris Locke (CS Computer Services),
No offence, but how can you possibly tell me that I have no valid reason to continue with XP.

I have just short of 39 years of computer experience plus postgraduate qualifications in computing.

This makes me feel that I'm a big enough boy to make my own decisions as to my operating system.

I do have Windows 7 and I really dislike it, it is the least used of four systems in my computer.

So let's come to an agreement, I won't dictate what OS you use and, I won't dictate which OS you use.

Last line should read:-
So let's come to an agreement, I won't dictate what OS you use and, I won't dictate which OS I use. :-)

Seb, Software has always had hardware and OS requirements. This is no different.
Clinging to a 15-year-old OS well beyond its lifecycle isn't going to be able to run all software written to current standards.
I have fond memories of my Commodore 64 but I'm not going to complain that Witcher 3 won't run on it.

Rolo, what is whitcher 3 @ where can we get it?

Chris Locke - The point was that the system requirements claim it works with XP and it doesn't.
I, too, have some computers running XP...and for good, valid reasons. Perhaps some of us built our go-carts with proper brakes and windshields.
The software works reasonably well on Win7 so I'll keep it.

Absolutely no problem to that. My -7 comments to your +2 proves that point.
Not sure what the 39 years of computer experience has to do with it though...

Chris Locke (CS Computer Services),
It means I have enough experience in computers to make good choices.
I tried it in Windows 7 and it works very well, I use it when I have to do so.
At other times I much prefer XP and therefore I work in that OS.
Sorry it causes you so much distress that I will not allow Microsoft to dictate to me.
End of this childish discussion as far as I'm concerned.

Chris Locke, You do indeed have the choice of machines. We all do. I think that you were just giving information, not criticizing. Unfortunately, as you may have noticed, our tones of voice, body language and facial expressions do not come across properly to strangers in texts and emails. Sometimes not to people we know well!

Chris Locke (CS Computer Services), I like Windows 98, XP, 7, 8.1, 10, Linux (better specify not a Windows OS) and would even still use Win 3.1 if it would run anything. I liked the way the entire program went into it's own folder in 3.1 instead of half the program going into a Windows folder. Guys I started when DOS was the only OS. Can you guess my age! Vista was good only because it created Win 7. The one I really hated though was Windows Me because it kept crashing the computers I was building for customers.

Adam ,

If you don't know what whicher 3 is how can you possibly know if you want or need it? Your question is kind .... let's say strange

Chris Locke (CS Computer Services), Have you ever tried running a car on a go kart track? It no workiee.

Chris Locke (CS Computer Services), actually XP was only discontinued because Windows is greedy, but the same can be said of all big companies. I loved my XP computer and only upgraded because my hard drive crashed after 9 years and because I also needed an updated video card, I just got a new computer instead of a hard drive. It was more cost effective. I didn't like what I heard about Win 7 or 8 so after I got my new computer, I just updated right away to Win 10. It was nice to see that Windows went back to the XP format so I didn't need to learn a new os. My biggest complaint with Win 10 is that it is too open and automatic, I am still looking for ways to limit my system so only I have control over it.

Technics,
My 1st computer job was in 1967 - punch cards in, and punch cards out!

My XP still runs well - using Firefox & Avast (other browsers & Anti-Virus programs no longer working).

TK, I do love the RAM and storage that I now have. I agree with your analogy about comparing cars and hybrids.

Nigel, Which, the XP discussion or the software?
