After creating an entry point for the IE, you should have an iexplore.exe file in your Thinapps folder containing the Acrobat Reader.
If you start the IE using this iexplore.exe file (double click in the explorer), it should start the IE in the virtual bubble of the Acrobat Reader an the plugin should work. For the first test, close all other open IE windows, maybe the IE is smart enough to recognize that another instance is open and uses this instance, instead of creating a new one.
Also I've tried installing IE as a ThinApp, I'm not sure how this can be done but I capture IE and when I try to add it on View Admin it comes up as Status Invalid and will not add it to the list of ThinApps. I captured it by just clicking on Internet Explorer button and choosing "Include an entry point for system installed IE", is this a valid way to ThinApp IE? or would we literally have to uninstall IE and then install again and then capture that?
For running the IE in a virtual session, your approach is valid, at least if you use Thinapps on normal systems. I don't have any knowledge about vmware View, so I can't say anything to your error. I've used this approach on the IE and it worked on stand-alone machines.
But for your captured IE to see the Adobe Reader plugin that is contained in another Thinapp package, you need to add an applink entry in the package.ini, so that the newly created IE only package see the content of the Adobe Reader package.
