I have a 32 bit exe file compiled with Turbo Pascal. I need to launch it. It worked well when I had Windows 7 32 bit, but now I’m on Windows 7 64 bit, and I get the following exception:
The specified executable is not a valid application for this OS platform.
To make sure it works on 32 bit systems, I launched the C# program in a 32 bit platform – it works.
So how can I launch a 32 bit exe file in 64 bit OS?
Thanks
Turbo Pascal could only generate 16-bit code, there was never a version that could create 32-bit executables. Running 16-bit code requires a virtual machine that uses the real-mode emulation support in the CPU (virtual 8086 mode). This emulation is not available if the processor is running in 64-bit mode.
You cannot run 16-bit processes on a 64-bit operating system. You may have a shot at getting it going with the DOSBox emulator.
