Castaway Stories: Problem when attempting to install

Hi there! So I'm trying to install Castaway Stories. BitDefender is turned off, and I extracted the .rar to a folder (I have also attempted the install without extracting first). I get the error message every time I try and start up Autorun.exe:

"A problem occurred when trying to transfer the file 'D:\[USERNAME]\Downloads\Castaway Stories\AutoRunGUI.dll' from the media. Do you want to retry to copy the file, or cancel the installation?" [Retry] [Cancel]


Pressing retry does nothing other than reload the error message.

Any help is appreciated c:

For the extraction use Winrar, not Winzip, Zip 7 or whatever other program.

Yup, I'm using winrar
