Are there any working gba emulators for Lenovo flex?

I have windows 8, if that bears any significance. Every emulator I attempt to download either stops installing at 100% without allowing me to complete the process, gives me an error message, or, in the case of no$gba, stops responding as soon as I attempt to boot up a game. Are there any emulators that will work?

I don't know, I'm on a mac and most of the emulators don't work. Luckily I have an old psp that I run old school games on. You could try looking at some emulators on youtube or www.coolrom.com
