After installing the XACT 5 release, users may get an error similar to the following after running a licensed program:
license for feature <feature> couldn't be checked out because invalid data was returned from license server
This may be due to the old, pre-XACT 5 license manager running on the machine. Kill the old license manager and deamon, and start the XACT 5 license manager program. While it is capable of reading the same license file, the new license manager program operates slightly differently that the one in the previous release.
