Old software is used today by millions of people around the world. For some it is out of necessity. For others, it is out of choice.
If you own an old Computer, it is likely to run legacy software. Your applications (and operating system) become older and more difficult to run on newer machines.
This is an issue if you prefer an older version of an application because you know how to use it. What would you do if the software is discontinued, or your old computer fails to beyond economical repair?

Ah! The days of Floppy Disks and MS-DOS applications from the 1980s, such as Lotus 123 spreadsheets. That takes me back. More recently, the explosion of the personal computer and Windows 95 from the mid-1990's.
All confined to history, or so you think. Would you be surprised if I told you that Windows XP was the second most popular operating system in the world at the point it was discontinued by Microsoft in April 2014?
This was four and a half years after Microsoft released two further operating systems in Windows Vista and Windows 7.
All brand-new software ultimately end up as legacy software. A standard pattern or lifecycle for all software broadly follows this process:
It is in our nature to stick with what we know. New software versions often confuse us, and means we need to learn the new ways of saving that file or putting that border around that image.
However, it is a step we all take, eventually. Next, we look at why you favourite old software doesn't work as well on newer machines.

Have you ever tried to install software you own on to a new computer, only to find this type of error message appear?
Software programs are written to comply with current operating system(s) are designed. This means when you use them, there is less likelihood of error occurring.
When vendors such as Microsoft and Apple release new operating systems, they ensure old system files and registry structures are retained for older software to continue working seamlessly.
However, this only goes so far. Software vendors like you to buy their new software. It's business, after all! Therefore, they do not retain legacy files and directory structures forever.
Once the supporting files are removed, or new features of the latest operating system start to interfere with your old software, it is usually time to ditch it and replace with new.
There are many reasons why old applications fail to work properly on new operating systems, including:-
Additional help is provided by vendors to assist with running older version of applications. We take a look at what this help is next.

Do not despair just yet if your old software does work with your new computer. There are a few tricks you can try that has worked for me and countless others.
Having trouble installing on later Microsoft Operating Systems? Try compatibility mode:-
VMWare or Oracle VM VirtualBox enables you to install older, compatible operating systems in to a 'virtual environment'.
This means you can load up your older operating system on your new computer and run your old software. The set-up can get quite technical, but is straightforward once you have done it a few times.
If you own Windows 7 Professional up to Ultimate, you can install Microsoft virtual PC and run what is called XP Mode (Windows 8, 10 and beyond do not include XP Mode).
Following the same principles as VirtualBox, this is Microsoft's attempts to aid backward compatibility with older software. It enables you to run your old software 'seamlessly' on a newer O/S.
What this means is a cut down version of Windows XP runs hidden in the background. When you load your old application, it looks just like it is running in Windows 7.
What is actually happening is the old software is running in a 'virtual XP bubble' which contains all the required files and settings to run your old software properly.
The image below shows Internet Explorer 6 running seamlessly on Windows 7 (IE6 is incompatible with Windows 7 or above).
If you have lost your old applications, there are many places to find them. eBay and other websites hosting legacy programs in the public domain, i.e. no licensing implications if you install, are easy to find with a little research.
My advice is to avoid using old software when they become troublesome to install or use.
Next, we look at the legacy software tutorials written for home computer users, covering Dell computers and the Apple iPad.
