I've just downloaded Primo2 for dad's phone (LG L9) because he explicitly wants iGo. [Please Register or Login to download file] I followed the instructions but I stopped at the end of A section. I have Primo2 folder on my internal storage and 6 different folders, 2 .zip files, 2 .dlls, sys.txt and Primo2.exe in that folder. I also copied voice and language packs in their appropriate locations Primo2/content/lang and voice. But now I don't know how to start the app, Primo2.exe is not valid Windows file and I don't know hot to run it on phone. Any help would be appreciated. Thank you!

In short, you downloaded the wrong Primo.

The LG L9 is an android phone, so you should start by visiting the Android section, for a Primo for Android. The one you have now, 2.4.9.etc, is intended for Windows CE5 and Windows CE6 devices. That Primo won't run either on the latest Windows phones, since they do not even run Windows CE.
