32-bit .NET app, 32/64 bit runtime coexistence?

[anders_gustafsson]

I have seen posts earlier that indicates that bith 32 and 64 bit runtimes could coexist. My question is simply:

Assuming a 32-bit .Net app, will it work with just the 64-bit runtime installed? (I tried, it did not)

If the app indeed needs a 32 bit runtime and another app requires a 64-bit runtime, should i then install both runtimes?

A 32-bit .NET app will require the 32-bit runtime.  Yes, you should be able to install both runtimes.
