single install - 32 vs. 64 bit files delivered
I have an InstallScript MSI. I want to have a single install that will install to 32 or 64 bit machiines with the same installation script. We have third party software that has 32 bit libs and 64 bit libs. The 32 bit libs have to be installed to 32 bit machines and the 64 bit libs have to be installed to 64 bit machines. I get the idea of creating 32 and 64 bit features and components. How do I configure the features and components so only the 32 bit libs are installed on 32 bit machines and only the 64 bit libs are installed on 64 bit machines.?
I have included the Not VersionNT64 condition on the 32 bit feature and the VersionNT64 condition on the 64 bit feature, yet both 32 and 64 bit files are being installed.
Look through the help files. Start with the "Targeting 64-bit Operating Systems" topic under "Installshield 2012| Target System Requirements". At the end of this topic, there are tips for doing exactly what you want.
Attempting to implement all the "helpful" IS articles was just confusing me and the issue at hand. What I have done is to create 2 features (one for 32, one for 64 bit components). Under each feature, I created a single component. I populated the component associated with the 32 bit feature with 32 bit file. I populated the component associated with the 64 bit feature with 64 bit files. Both features are checked in the Setup Types for both custom and complete. In the Condition field for the component associated with the 32 bit feature, I put in "NOT VersionNT64". In the Condition field for the component associated with the 64 bit feature, I put in "VersionNT64". I have tested this and it seems to work.
If the different libraries you are installing are all compiled as 32 bit, you can use one installation. If one set of libraries is compiled as 64 bit, you'll have to create two installations from the same project.
And yes, the IS articles about 64 bit installations could definitely be better organized and more complete.
This keeps everything simple and the installation is seamless as far as the user is concerned and he still sees a single installer EXE.
