I cannot uninstall/reinstall the game?

[Gjunki]

So I deleted the blade and soul folders a long time ago (did not uninstall through control panel) because i thought i quit for good. Now i want to come back to the game and see whats changed but when i went to try to reinstall the game it gave me this: 1628: Failed to complete installation. I've tried everything under the sun. I redownloaded the NCLauncher, I tired uninstalling from control panel (which hasnt succeeded because it still thinks the game is installed), and I've manually deleted anything that has to do with BnS. The annoying part is I still cant get the damn game to install again. Can anyone help me with this issue? Thank you.

PS: I'm using installshield wizard to install, on windows 7. Could it be an issue with that?
