There is a problem with IE’s caching mechanism that causes this symptom:
When you click on a Java Web Start link for FactoryPMI, you get the error message:
“Unable to launch the specified application”
with the details:
An error occurred while launching/running the application.
Category: Invalid Argument error
Could not load file/URL specified
This is caused by IE either not creating or deleting the JNLP file from its cache
before the JWS system can load it. It is usually caused by IE having a full cache. To empty the cache, go to Tools -> Internet Options -> Delete Files.
This should fix the problem. For more details, see:
