xen app hosted client - can not uninstall - repair - or reinstall

I need help.  I cannot remove/repair/reinstall citrix client xenapphosted_11.0.150 in a couple window 7_x64 boxes.

We have been using this client for quite some time without issue with use with a few old presentaion servers.  While testing a XenApp Fundamentals 6 server I installed Citrix Receiver 13.1.0.89 on a couple machines (that already had xenapphosted client installed) to help test the new fundamentals box.  Installing the receiver seems to have broken the xenapphosted client.  I uninstalled the receiver with out issue, but the xenapphosted client will not uninstall.

I have searched online, and found various how to's (mostly from citrx) on how to manually remove the xenappclient.  None have worked so far.  

Does anyone have any knowledge on how I can manually remove all traces of xenapphosted client, so I can reinstall it again?  Or have any advice on what I should do so I can reinstall the xenapphosted client to make it funcional again?

On one machine, I followed citrix's instructions to delete many dir's & files on the pc, removed many reg key, but no luck.  I do not see the client listed in the add/remove programs area anymore, but when I try to install the xenapphosted client now I receive a error "The installation ended prematurely because of an error".

This was also the error I would see when I originally tried to uninstall the program from the add/remove programs.

Checking the event log after this error reveals 2 entries.
