Good morning,
Yesterday I had an issue with CAD installation for UCCX 10.5. As you know before installing CAD on Windows PC it is necessary to run Client Configuration Tool. However, when we run it on Windows 7 PC, we received an error “Default entry: Awaiting return value from uploader.exe” and the execution of Client Configuration Tool stopped.
The solution is here. This problem was caused by Java. As far as our PCs update their Java all the time, they had the newest Java, of course. In order to solve the issue we uninstalled current Java on this PC first, then Java version 1.7 Update51 was installed. Super! Now our Client Configuration Tool was executed without any errors, and we could run CAD installation then.
Hope my advise will help you, if you face this problem in your UCCX.
