I have Plazmic 4.2 installed and would like to install 4.5. I get the following error on installation:

Fatal Application Error.
This application has unexpectedly quit. Innvocation of this Java Application has caused an Innvocation TargetException. This application will now exit. (LAX)

When I click on details it says the following:

java.lang.NullPointerException
