I'm sorry I'm not clear about your problem. Are you saying that you have created a QVW which is of 50 MB size and takes a lot of time when you open it? In that case you can reduce the data and reload.
You can also check how much memory it is taking by looking at your system's task manager.
How can you create an .exe file without the proper license for it?.
In any case, an .exe file needs to include the whole software plus the data plus the application.
60Mb doesn't seem so big from that point of view
It is better for you to make a QVD file and use it as a data source file for boosting your QlikView performance as well as reducing the qvw/.exe file size.
