Can a 64-bit program use a 32-bit DLL?
On 64-bit Windows, a 64-bit process cannot load a 32-bit dynamic-link library (DLL). Additionally, a 32-bit process cannot load a 64-bit DLL. However, 64-bit Windows supports remote procedure calls (RPC) between 64-bit and 32-bit processes (both on the same computer and across computers).
How can I run a 32-bit DLL on a 64-bit machine?
1 Answer
- Right click on your project in Visual Studio and select Properties.
- On the Build project properties tab ensure that the Platform target drop down reads “x86” instead of “Any CPU”
Can 64-bit python load 32-bit DLL?
64-bit EXEs cannot load 32-bit DLLs. (And vice versa: 32-bit EXEs cannot load 64-bit DLLs.)
Can I run a 32-bit app in 64-bit Windows?
WOW64 is the x86 emulator that allows 32-bit Windows-based applications to run seamlessly on 64-bit Windows. This allows for 32-bit (x86) Windows applications to run seamlessly in 64-bit (x64) Windows, as well as for 32-bit (x86) and 32-bit (ARM) Windows applications to run seamlessly in 64-bit (ARM64) Windows.
How can I install 32-bit on 64-bit?
Newer operating systems do have the option to use 32-bit applications on 64-bit architecture. This is achieved by having two “Program Files Systems” on the same computer. The 32-bit File system is stored as “Program Files(x86)” this way Windows can identify a 32-bit application and provide the accurate “.
How do I run a program in 32-bit compatibility mode?

How do I connect my 32 bit Linux to a 64 bit library?
You can’t directly link to 32bit code inside of a 64bit program. The best option is to compile a 32bit (standalone) program that can run on your 64bit platform (using ia32), and then use a form of inter-process communication to communicate to it from your 64bit program.
What happens if you run 32-bit on 64-bit?
To put it in simple words, if you run a 32-bit program on a 64-bit machine, it will work fine, and you won’t encounter any problems. Backward compatibility is an important part when it comes to computer technology. Therefore, 64 bit systems can support and run 32-bit applications.
What is the difference between System32 and SysWOW64?
System32 is the 64-bit Windows system directory and SysWOW64 is the 32-bit Windows system directory — entirely the opposite way around to what the directory names would suggest. In Windows, there is a “Windows” directory and a “System” directory, and this has been true all of the way back to when Windows was 16-bit.
Where do 32-bit DLLs go?
The 32-bit one goes into C:\Windows\SysWOW64, and the 64-bit DLL goes into C:\Windows\System32.
