We are using the Aspose.powerpoint component (Java) to dynamically generate presentations from images in an image library on the web. This subsequent ppt file is then downloaded to the user’s machine for them to use. The people who download the presentation on a Mac machine and work with it using MS PowerPoint (v.X, for the most part) sooner or later have the program crash on them. I had several users complain about Powerpoint freezing up on them and having to ‘Force Quit’ it. Other users had Powerpoint abruptly crashing. Has anybody else had this problem?
The error log starts as below:

Hello Sunbomb.
According to a component’s name (aspose.powerpoint instead of aspose.slides), you are using outdated version. Please check current version of Aspose.Slides for java, there was a lot of bugfixes since component’s renaming.
Hi Nikolay,
We purchased our license last December (for Aspose.Powerpoint), so it should still be valid for Aspose.Slides, right? I have an issue where I cannot test the Java code that I am using with a main() method (this is described here: ), so I cannot be sure. I renamed the Apose.Powerpoint.lic file to Aspose.Slides.lic and the one time I tried to apply the license file (through a web application call), I got an error that basically indicated that this did not work.
Thanks
I upgraded the jar file to aspose.slides.jar. Then I changed the name of the Aspose.Powerpoint.lic file to Aspose.Slides.lic. Also I specified the license declaration in the code as com.aspose.slides.License and this worked. So thanks.
