Sorry for not commenting earlier, but I actually managed to install Run GPS earlier today. It seemed like the file had been broken the first time I downloaded it.
- Do you have enough free storage? Main memory and SD card?
- Did you try using a different installer? (e.g. copy the CAB file on the device and then start usint "File Explorer" on the device)
I just bought the HTC HD2, but I cant install Run GPS. I downloaded the CAB file on the phone, but when I try to run it the install is cancelled as soon as it starts and the phons says can't install.
