I made a simple msi project and it has some filrs and registry entries. It installs fine in both 32 bit and 64 bit windows but the registry is not showing up in 64 bit windows..... its showing in 32 bit. Is this a known bug with Installshield???
This is a limitation of Windows Installer. To install to 64-bit registry locations, the component must be marked as 64-bit, and the install must also be marked as 64-bit. Once that's done, the package cannot be installed on a 32-bit system.
There are workarounds involving custom actions that write to the registry directly.
I just got done chasing this issue around with generating a 64 bit and 32 bit install from one project. After talking with support, I settled on the following approach.
1. Create a hidden feature (example: Feature64) under the feature that creates registry keys. 2. Create a new component under Feature64. 3. Mark that component as 64 bit 4. Create duplicates of the registry keys in this component.
This allows you to have two builds one for 32 bit and one for 64 bit, where ReleaseFlags are used to include the 64 bit hidden feature for the 64 bit build.
