While installing HD 5750 in my PC, I got an error that looked like this:
Setup application has stopped working: Appcrash Setup.exe
XFX Card Installer
I was using the Driver CD that comes with this card.
The card I have is: XFX ATI HD 5750
To solve this issue, you need to download New Drivers from ATI’s website. It’s a Simple Solution : ) But it works: you will not see the error again.
I had to download the new 64 Bit WIN 7 driver pack.
