I want to update my site to the latest GPS Tools so I am testing this locally. I am using XAMPP to do this and start woth the cjlib component. Unfortunately I get an error message while doing the update. The message can be found in the attachment. It is in dutch but states that a path is not a folder and that the copying of files failed.

The translation of the dutch message is: 

JFolder::files: Path is not a folder

I tried all possible options to install the extension, but nothing worked. Solutions based on the message do not give a solution as well.

Can someone give me some guidance?
