Where can i find turbo c for windows 7 32 bit

Not sure what you want?
If downgrading to winXP 32 - Yes, But you need to go to the Dell's websit and download ALL the drivers for WinXP 32 bit and individually install.

If this is so that you can run turbo C for Windows XP, It can be installed and run on win 7. I can Run Basic profession (pre XP) on a windows 7 32 bit operating system. For windows 7 64 bit, the program to install can not contain any 16 bit code (16 bit code is OK in win 7 32 bit OS).

Basic Prof will not run on win 7 64 bit, But there is a work-a-round called Dos box.
