Just came across this issue when I was testing the "double click .mpk file" mod installation method:
16.9.14 15:47:09.7531: Error:
Unable to install mod: C:\Users\Flessen\Documents\VoidExpanse
Exception System.IO.FileNotFoundException: Mod not found

16.9.14 15:47:09.7901: Important:
Button BtnOk focused
I'm guessing, looking at the log, that the installer doesn't like spaces in the directory, as I was trying to install it from:
"C:\Users\Flessen\Documents\VoidExpanse Mods\"
Hm, interesting. Thank you for reporting! We will investigate the cause.
Fixed in just released v0.7.8.
You guys are amazing :D
