The catalog directory is the location of your IQ .db file (called the catalog).
In the catalog directory, is there a file with the .lmp extension? If so, what are the contents? What type of license did you generate? Development? Standby? Production?
In your startup output, you should see something like this:
I. 02/17 17:07:20. 0000000000 Using licenses from: C:\Programmi\Sybase\SYSAM-2_0\licenses\ExpressEdition.lic;C:\ProgramData\SybaseIQ\demo\ExpressEdition.lic
Another useful link on this topic is here: SAP IQ Express 16 report license error after 30 days. But Express is not Trial, so why is there this license error?
It refers to the Express Edition, but the basic steps are the same. The only changes would be the values for PE and LT.
