x64 Versions and setup

I'm porting our Watchdog application to VC++ 2005. It's a lot of work, and the end result should be no difference for the user. But it's a step I'd have to take eventually.

One advantage of this port is that I'll be able to create 64bit versions of my applications. Some people think it's to early to worry about 64bit, but I don't believe it is. Every new PC sold nowadays is capable of 64bit. And I see a rise in people using a 64bit operating system. Also, it doesn't hurt to be prepared. It's something every misv will have to do eventually, so why not do this early on.

One thing I don't want is a separate download for 32 and 64 bit versions. The installer should check the operating system and install the 32bit or 64bit version. Maybe create an option to install the 32bit version on a 64bit system for compatibility. So I checked Inno setup and apparently they have everything I need (again). Simply set that x86 and x64 are allowed and your setup will automatically detect a 32 or 64bit install. Then, separate the 32bit and 64bit files and add a check with the IsWin64 function to install the correct file. That's all. The setup itself stays 32bit, but that shouldn't be a problem.

It will take some time to create the 64bit versions, and I'll need to test the new system on 32bit and 64bit operating systems. But you can expect 64bit versions of the Kwakkelflap programs in the near future.
