64bit Program Cannot Start(0xc00007b Error)

[alanccc]

Hi,

I am using Delphi XE3 to build a 64bit Program under 32bit system. However, whenever I run the 64bit program in a 64bit virtual machine, I will always get an error message “The application was unable to start correctly (0xc000007b).”. I try to use Remote Debugger to debug the program. However, even when I starting the debug by clicking F8, I will still get the error message. So I cannot even access the first source line of the program before the error occurs. In such a case, how to debug such a program and find out the actual reason that cause the error?

Thanks

Mostly the issue is that your program is trying to load a DLL that is not there under the 64 bit OS.
Use dependency walker to find out which DLL dependency is missing.
Procmon could be also be useful in these cases.
