Neither install or no_install version will run

I downloaded the Community Edition but it wouldn’t install - no errors just disk action then nothing. Then downloaded no-install version but when I double-click on Visual Paradigm for UML, it I get the page fault indicated below. I tried invoking from command line with
jre\bin\java -cp vpuml.jar;vpumlresources.jar RV
In that case lots of disk action but no errors no GUI display. . This does not encourage me to purchase the product even tho it looks like a potentially valuable tool. Any suggestions? Also I never received a license. Should I have received a license for the Community Edition?

Hi Mac,

Java has a problem with Windows 98 which is outlined http://weblogs.java.net/cs/user/view/cs_msg/1767 .

To fix the problem, use the following command:
jre\bin\java -Dsun.java2d.noddraw -cp vpuml.jar;vpumlresources.jar RV

Hope this helps.
