The assumption being that a false signifies a 32bit environment. Raymond Chen described this approach in a blog article. Determines whether the current operating system is a 64-bit operating system.
#Is my system 32 or 64 bit windows 32 bit
And now they all run at 32 bit and is causing the software to work slower it seems. Yea, but my Adobe products used to always run 64 bit before I updated windows.
It will be like playing basketball using only one arm: possible, but not optimal. None of them will prevent 64-bit software running at 64-bit.
#Is my system 32 or 64 bit windows full
In fact, you can probably get the information from a conditional supplied by the compiler, depending on which compiler you use, since the size of the pointer is known at compile time. The important part: A 64-bit processor can run both 32-bit and 64-bit operating systems and programs, but you won’t be running it at full capacity if you’re using a 32-bit Windows version. A 32 bit pointer indicates a 32 bit system, and a 64 bit pointer indicates a 64 bit system. And then you just need to test the size of a pointer, for instance. If you call IsWow64Process and TRUE is returned, then you know that you are running on a 64 bit system. Call the function and read the wProcessorArchitecture member of the SYSTEM_INFO struct that the function populates.Īlthough it is actually possible to use IsWow64Process to detect this. The Win32 API function to detect information about the underlying system is GetNativeSystemInfo.
