We have an application that needs to be able to be installed either on a 32 bit or a 64 bit platform. We have two separate releases. We would like to have one installer that would call the 32bit or 64bit installer based on platform. I am not even sure if this possible, but if it is could you point me in the right direction.
A lot of this depends on information you haven't mentioned. For example, an InstallScript installation can write to either 32-bit or 64-bit locations. It can also act as a launcher to launch eithe ra 32-bit or a 64-bit MSI. An MSI, however, has to be either 32-bit or 64-bit; it cannot be both. However a 32-bit MSI can generally install onto a 64-bit machine, depending on whether you actually need to write to 64-bit locations.
If you're going down the MSI route, we also have some exciting changes planned for our next release to assist in delivering the correct MSI in a single installation package. So keep your eyes peeled for that.
