Now this was an interesting exercise!!
This morning I checked my app and Checked the Global Extensions it said NetTalk 8.38.
I checked the dll's in the accessory\bin folder and they were the sames as in my application folder, so far so good right.
Well the libraries are from the previous version of NetTalk installed which was 8.35.
I downloaded the NetTalk saf file again and re-installed 8.38. Compiled my app and checked the dll's in the app folder, now they were dated 1.15.2015.
Uploaded to our site and all works
. Evidently the first install failed to put the dll's in the accessory\bin folder.
ALL is GOOD and I can break into my happy dance now!
