I have downloaded the Premiere 10 trial and run the exe file in...\Adobe Premiere Elements 10\PRE 10\ElementsSTIInstaller, However, I can not find the program on my computer.  Can you please tell me the procedure to install the program following the down load???

P.S. the download assistant does not install the program automatically and I have restarted the computer.

Thankyou
