Unstable (Windows 8)

Plus: in principle nicely done, performed tasks are stored, it can be adjusted 3 different difficulty levels and several children it can register (under different names or even the same child) under his own name. As a reward for correctly performed tasks games are unlocked.
Minus: the voice sounds a bit tinny. The biggest shortcoming in Mathe1 is the instability in Windows 8. The program repeatedly stops responding when the geometry tasks already on the first day, so it had to be closed in the Task Manager. When Maths2 also purchased this error has not yet occurred, even though the program is structured very similar.
Given the instability, at least on Windows 8, I can not recommend this program for Windows 8. How stable the program under other Windows Betriebssystemem running, I can not judge.

Another note for installation: In another judgment states that the CD must always be inserted. As I have found by chance, it depends on how the program will be installed:
When you insert the CD of Installation Manager starts. Following this, only then will the program, but does not install the additional data on the hard drive. Ie when the program starts, the CD must be inserted.
However, when installing via Windows Explorer (double-click on Start or install or something like that, but not to autorun) installed, then you can select whether only the program itself or the complete CD to be installed on the hard drive.

Based on the above knowledge and the comparison with the educational software from another manufacturer, can I improve my rating to one star. The instability unfortunately still occurs. On the other hand "play" our children very happy with Math 1 and 2. Without crashes I would give the program 5 Stars.
