Dear Unity Support,
I have big problem with Unity. Neither of Games made in Unity Engine work on my PC. Even when I tried to install and run Unity ENgine by itself, it doesn’t work.
When I launch the application, almost immediately I get message that “program has stopped working”.
In details there is exception number c000001d
It seems to be a core problem with Unity Engine, because neither games in Unity and nor engine itself don’t work. Even web unity player doesn’t work, everything was installed correctly, but dont work. I tried everything and still don’t know what to do.
Yes, I have old PC especially the processor, so the idea here is that Unity engine requires some function which is not supported by my processor. (For example like windows 8 I also cannot run, due to missing öne CPU function)
Here are my specs: AMD Athlon XP 2600+ (1.9 GHz), RAM 1,75 GB, Graphics: ATI Radeon X1650 Pro (256MB) , Windows 7 Ultimate.32 bit
Pls, don’t write me to update my drivers, or reinstall windows, I have the only one drivers I can have (All other games and programs work perfect for me, using the graphic card at maximum). Everything else work so fine except those based on Unity.
Even I tried install two operational systems on my PC, win XP and WIn 7 and in XP it doesn’t work too… 
I run it as administrator, in compatible mod, nothing helped.
So I ask here, if you know what can i do, thank you very much in advance. Karel
