Slitherine

I had version 1.4 installed on my Dell laptop (vista basic) but trying to install the 1.5 patch brought up "Launcher Error: Failed to read setup engine".
I uninstalled the whole game and reloaded 1.2, but upon trying to install the 1.5 patch I get the same Launcher Error again.

Please help!

No matter. I tried again and installed 1.2 then 1.4 then 1.5 and all seems to work now.

Computers. I will never understand them!

It could have been a corrupt download as all installers contain everything from previous versions.
