Running 32bit .NET application in 64bit OS, is it really bad?

I understand that we can compile a .NET Application by targeting AnyCPU which will cause to run 32bit in a 32bit OS and 64bit in a 64bit OS. However there was a reported bug* on a 64bit OS that my app was giving an error and the solutions for that, I need to target x86.

Get HDD (and NOT Volume) Serial Number on Vista Ultimate 64 bit

I was once looking for getting the HDD serial number without using WMI, and I found it. The code I found and posted on StackOverFlow.com works very well on 32 bit Windows, both XP and Vista.

We have a WinForms app that runs fine on x86, but has many third-party components that make win32 calls. To get the apps to run on x64, I now compile for the x86 platform.

ActivePDF Toolkit in Windows Server 2003 x64

I've recently migrated my app to a 64bit OS (from 32bit Win2k3) and am finding that one dependency - ActivePDF simply won't run under x64. I'm not sure if its by design, or just that it hasn't been tested for 64 bit operation. Is there anyway to get this to run under 32bit mode somehow? ...
