Hello,
did you start the installation as administrator ? This should possibly solve the problem.
And it's certainly not Captain Sim's fault that you can't install it, more than 100 people have already bought this product. However, I have only read about one or two cases in the forum where this problem occurs with error 24.
I did some searching on the internet at ..... Maybe this will help...it's not about a Captain Sim product, but probably the same principle...
