Can't get jingle/call icon in spark

When I run Spark, on systems with audio/video I cannot get the jingle call button to come up on Spark. I have two different vista machines with two different anti-virus protections and have the same issue.

I have googled and searched the forums, but can’t seem to find a solution.

Environment

Spark 2.5.8 - using 2.5.8 .msi installer

Windows Vista

Anti-Virus: Macafee/Kaspersky

I get this message in the log file after starting up.

Exception on commit = java.io.IOException: Can’t find registry file

I heard there might be issues with the msi installer. Try uninstalling Spark, and deleting the Spark folder in Program Files and the Documents and Settings folders. Then install the Spark using the exe installer.
