I need to know the difference between Framework and Framework64 folder C:\Windows\Microsoft.NET folder and please don't make assumption that I know basic things that you already know.

For example, I have ASP.NET sites on 32 bit windows 2003 R2 / IIS 6, and I am moving them to Windows 20112 R2 64 bit / IIS 8.5 by building sites and moving the code etc. I have also Apache sites on Linux but that is another issue.

Here are my questions

1-)  Is it safe to assume that all the web app hosted on Windows 2003 R2 is 32 bit applications, because OS is 32 bit.
2-)  If not, how i can determine which app is 32 bit and which one is 64 bit
3-)  When I run commands such as caspol and aspnet_regiis -ga on Windows 2012 R2 during building sites , Should I run them in   C:\Windows\Microsoft.NET\Framework64\ or C:\Windows\Microsoft.NET\Framework\

( I am aware that I should run these commands in the subfolders of v4.0.30319 or v2.0.50727 depending on the site. But that is not my question. My question is which folder ; framework or framework64 )

So far I was running all the commands in C:\Windows\Microsoft.NET\Framework

4- ) if that is the case, meaning I should be running them under C:\Windows\Microsoft.NET\Framework on Windows 2012 R2 / IIS 8.5 , then in which case I should be running them in C:\Windows\Microsoft.NET\Framework64 folder.
