How to let Learn to Speak German 8.0 run on Windows Vista

Have you check the hardware compatibility on the Computer? There is a minimum spec requirement to run windows 8. Is it a 32 or 64 bit windows 8? The HP A720N was available for sale in Sept. 1, 2004. I doubt if it will run win 8. The Ram and Graphics are going to be a big issue. Take a look at this Min. Requirements: http://windows.microsoft.com/en-us/windows-8/system-requirements If you can, return Win 8. Looking at your specs, I don't think you can run Win 7? http://windows.microsoft.com/en-us/windows7/products/system-requirements Perhaps Vista.

Go to custom Install and disable the installation of DirectX and QuickPlayer. It worked for me!, Good luck!

According to the company's website (http://www.amazon.com/Learn-to-Speak-German-8-1/dp/system-requirements/B00005TQ1E/ref=noref?ie=UTF8&n=229534&s=software), it works on Windows up to XP. It doesn't list Vista or Windows 7 as options. And it looks like others have had the same problem (http://www.fixya.com/support/t5241472-learn_speak_german_version_8_0 and http://www.fixya.com/support/t514069-let_learn_speak_german_8_0_run_windows). However if you have the Professional, Ultimate, or Enterprise version of Windows 7 you might be able to run it in compatibility mode (http://www.microsoft.com/windows/virtual-pc/download.aspx or http://windows.microsoft.com/en-US/windows7/Make-older-programs-run-in-this-version-of-Windows).
Hope this helps!

Try running the program in compatibility mode. Right click on the icon used to start it, go to compatibility and change it to Windows XP. If this doesn't work, the program is not capable of running in Windows 7 so you will need to downgrade Windows or upgrade to a newer version of the Learn to Speak English software.

Maybe it's not compatible with Vista. Or the program for that CD to run is not installed yet on your Vista.

If a program cannot be run under Windows 7 because of compatibility issues you have to right click on the executable file that will start the installation and click Properties. Select Compatibility tab and check the Windows version you know the program worked with before. You can find more about this Compatibility issue on Microsoft website: http://windows.microsoft.com/en-AU/windows-vista/Make-older-programs-run-in-this-version-of-Windows
Also after you install the program you most likely will have to do the same for the application file.

It may not be compatible with XP. Look on the back of the case and check which OS it is for. Sometimes the websites that support these have a patch for when you upgrade. I have had this problem with some of my software every time I've upgraded Operating Systems.

I don't think the program is compatible with Vista. Were you running Vista when it worked a year ago ?

First ensure you purchased the full version and not just the demo, in which many features are non operative, in that case it will be normal.
Most probably the disk is dirty, defective or scratched. If it is dirty you can wash the cd in cold water (no soap or cleaning products), and then dry well with a soft cloth, taking care not to leave hairs or wet spots before trying again.

You can try to repair the files.
Do you have Roxio on your computer?
