It's supposed to be in\Program Files. But because it's up to programmers to choose the folder usually even x64 programs put themselves in\Program Files (x86).
\Program Files folder
/Programs Files (x86) Folder
Programs and programs(86). Found under C:
Program files
Yes
In the program files folder in your hard drive.. 32bit programs will go into a folder called Program Files(x86)
Unfortunately, the older versions of OBS are not available on the Mac platform, which is why it always gives you a folder when you try to install it.
I don't think you can install anything for a 64 operating system unless requirements state ok for both. Most downloaded programs will end up on disc "C" & if you scroll programs in yo9ur comp. All programs appear alphabetical. (No folder-just appears with programs if is indeed a program.
Winnt.exe is the 16-bit version of the setup program and Winnt32.exe is the 32-bit version. Both are located in the \i386 folder on the CD. You can use Winnt.exe for a clean install or an upgrade on a computer running windows.
It installs itself over top of the old version. If you expect a problem then copy the World of Warcraft folder to somewhere else then run the install on the Burning Crusade DVDs.
Basically the same way you install other programs. Normally you would run an executable in the installation folder; this executable is often called "Install.exe" or "Setup.exe".

Go into the programs folder in Program Files on your HDD. There should be something like an uninstall.exe. This should also be in the start menu folder that gets added when you install. If you can;t find that then use the add/remove programs featured in windows.
