The call stack shows it is an <equals> tag.  You can use the expressions
window to view a tag instance’s xml property to see which tag it is.

In this case, it is:

<equals arg1="${flash.sdk.swfversion}"
arg2="${flash.sdk.default.swfversion}"/>



It appears that the install script is expecting the versionID in the
installer config to be 17.0b
