Default WMP runs 32-bit in 64-bit OS

[Phreonn]

This is rather annoying since I'm using a 64-bit OS, set WMP to load in 64-bit, and using a modified plugin to give me better functionality for WMP x64(but not WMP x86).

Since uTorrent is a x86 app I suppose it is using some execution method that runs x86 apps. Can this be changed to run x64 apps also? This is probably a WMP specific problem since it seems win7 is internally choosing to run the 32-bit version to match that of the application. (e.g., if uTorrent was 64-bit win7 would chose the x64 version).

From what I know Windows 64bit runs all 32bit applications using emulation.

But question is what relation is with Windows Media Player and uTorrent?

uT just tells windows to open the relevant file. It doesn't try to be explicit about 32-bit or 64-bit. It doesn't even pick WMP, it just literally calls shellexecute on the file.

And since uTorrent is a 32-bit program windows internally decides to execute WMP as a 32-bit program.

"he CreateProcess and ShellExecute functions can launch 32-bit and 64-bit processes from either 32-bit or 64-bit processes with certain limitations."

It seems that all that needs to be done is is disable Wow64DisableWow64FsRedirection. (maybe add a checkbox to enable/disable this).

Eeeh, it's not really a good idea to do it except in special cases.

We're gonna have a 64-bit app eventually, so, just wait for that and deal with it until then.
