I have used OpenIV before on my old computer, but when I switched to a new one, re-downloaded it, and tried again now it's not working like how it did.

I need some help, for whatever reason when I try to initially setup the OpenIV to my GTA IV file, it doesn't read that there is a file, but there is.
It's not giving me the full list so I can't just select my .exe file.

On my old computer it automatically found my .exe file, and now it's not at all.

I don't know what is going on, how to fix it or anything.  I'm dumbfounded on how to explain it.  I realize I'm not giving much information to help solve the issue but I'm not getting any information to provide.

If any one know, please help.

You need just select folder where your GTAIV.exe is located.

See I had the same problem on 3.0 Version with GTA 5 and it is not finding GTA 5 like I am physically looking at it on my desktop but when I click desktop it isn't there.
