The App-V Sequencer has detected a directory that contains 64-bit and 32-bit executables and/or dynamic-link library (.dll) files that depend on the same side-by-side assembly. Typically, the Sequencer creates private side-by-side assemblies for all public assemblies that are used by the package; however, it is not possible to create 32-bit and 64-bit versions of the private assemblies in the same directory.
If the Sequencer detects a single conflict, it will perform the following actions:
Remove all of the existing 64-bit private assemblies in the entire package, whether or not the directory has a conflict.
Create only 32-bit versions of the private side-by-side assemblies.
You should natively install public versions of all the required 64-bit assemblies on the computer running the Sequencer and on all App-V client computers.
To locate the required existing public assemblies, open the directory where the package is saved and look in the VFS folder. For example, if the package root is Q:\MyApp, when you sequence the application, look in Q:\MyApp\VFS\CSIDL_Windows\WinSxS\Manifests and locate all of the existing public assemblies. The 64-bit versions of these files will always start with the following text at the beginning of the manifest name: amd64…. The exact name and version of the assembly can be found in the associated manifest file.
