1. Check for Windows updates and install these
2. Install again the redistributables on your machine Visual C++ Redistributable Packages für Visual Studio 2013
3. Set the programm to run in compability modus (Right mouse button →Panel “Compability” → Start Programm in compability modus as Windows 8 or Windows 7
4. If nothing helps - you are not allown, you can see application fails to start after 8.1 upgrade

1. Consider installing Windows 7, in normal case it works on your machine
if this not possible:
1. Check if you have Service Pack 3 (Windows XP SP3) installed, this is required!!! This is Windows XP SP3 . 2. Install again the redistributables on your machine This redistrubitable package from Microsoft - the x86 (32 bit) Version
