I was just trying to warn those who are not capable to recognize what is the problem with upper commands when they enter it and cmd report error.
The reason is that I have to work with Statistica 5 (software from Statsoft) to finish something for my PhD. It's 16bit application and runing on older OS, works in XP untill you want to draw graphs (it will not crash if you change wow32.dll, I fix that on one of my machines but that was bothering). Works fine on Vista 32. I don't have time to try make it run on Vista 64 (I've installed recently) or to buy and install newer version of Statistica and I need reliable software in this moment.
Second reason is, I have piece of hardware in device manager that was not recognized after I've installed all drivers from HP website for my notebook. I was thinking, maybe there is no 64bit drivers for that device. After I switch back to Vista 32 it's still there but like I sad, I don't have time to that now, and when I finish that for PhD I'll try Windows 7.
