Restart you PC and try to install ignite after that.
if the same problem occurs, go to your local disc - aeriagames.
if theres other folders than the games of aeriagames //Downloads,etc// delete them.
If this still don't work, check your processor and check if any igniteis running in the background. fail-install occurs, rarely but check anyways.
If you only want ignite for the rename card, tell me your character name and i will send a 7pk to you.
