Scome version is not loading in Browser and its uploaded in moodle


we have License version of Lector 2004.

I am facing some problem in viewing the course in browser.

I have developed the learning unit using lector 2004 and i have published that in to Scome by that way we are using Moodle server in our company, so i have uploaded the published scome version in moodle.

When i tried to view uploaded scome it was working fine in Windows XP system but in Windows Vista PC its is not working but its working some system.

Even i have tried to reinstall the Java plug in but still its not working.

Can you please suggest how solve the issue.
