hi friends,
I am adding custom prerequisites using Bootsrapper Manifest Generator in VS 2008. In the Install conditions we want to specify the architecture like x86 or x64. But i have the doubt in specifying x64 architecture..

Generally i using AMD64 for 64bit system checking and working correctly. But when i cehck the discussion of BMG they use as differently.. Check the following link..

So what is the best method to check x64 from the following...? (i used first one)

1. < BypassIf Property =" ProcessorArchitecture " Compare =" ValueNotEqualTo " Value =" AMD64 " />
2. <BypassIf Property="VersionNT64" Compare="ValueNotExists" Value="N/A for ValueExists and ValueNotExists" />
3. <FailIf Property="ProcessorArchitecture" Compare="ValueEqualTo" Value="IA64" String="InvalidPlatformArchitecture" />

Also i want to know how AMD64 is different from IA64. Basic i know that IA from Intel and AMD from AMD..But how different in this scenario? Any article link or help? If you have any article about the install conditions please provide that also

AMD64 is basically x64, which is a certain flavor of 64-bit architecture you could look at as an extension to x86. IA64 is a completely different and rare architecture "Itanium" based on a full 64-bit CPU. Because it's completely different as well as very rarethe vast majority of apps don't support it.
