As a FileWave user you may have noticed some issues with different Adobe Plugin installers.  

Shockwave

When you first download Shockwave Player and open the DMG, you are presented with a file that has a .pkg filename.

Right clicking on the .pkg and selecting “Show Package Contents” give us the all of the parts that are going to be installed. We discover that there is a compressed file inside the pkg installer (Archive.pax.gz).

Delivering Filesets that contain Adobe PKG's might cause the installation to fail.

Adobe provides a tool called Adobe Application Manager Enterprise which is used to package Adobe installers into Apple's PGK's for mass deployment.
Unfortunately there is a problem with the FileWave Client in handling the post-flight scripts of Adobe PKG's. That might cause the installation to break.
