 * I solve this problem, I found that my istallation folder don't have an DirectX9 directory, I only have the WMF directory. Then, when the Premiere Pro setup reach the DirectX9 installer portion, this fail to load the required DLL because setup not found the DirectX9 path in the directory structure. I solve this very simple: uncompress the original trial version and this creates the DirectX9 directory structure plus the WMF directory and the setup files, copy the DirectX9 structure in your path of running setup an voila..... this works for me.

 * My problem was that when I unzipped the "PremierePro1_5_Tryout.exe" I didn't unzip it with the "use folder names" box checked within Winzip.
