Today we had to a few issues witha program that uses java on my scripting machine. We did a few installs of the JRE and also updated IE from 6 to 7. Now QTP will starts to open. I get the Lisence splash screen, click ok, then the QTP screen opens and then closes. The program never comes up.
Have you tried a clean uninstall then reinstall of qtp? Or even a 'repair' install or running quicktestprofessional.bat in the /bin directory? In the past I have seen issues with video card drivers cause that behavior too.
