XF 1.5 Error installing add-ons

[FedericoS]

Hello everyone!
When I try to install an add-on on my fresh-installed XF 1.5 Forum, it gives me this error when I try to upload a XML file:

The files associated with this add-on could not be found. Please upload them and try again.

I uploaded all add-ons files correctly. But it keeps to give me this error.
Thanks for reading

It sounds like you are uploading the files to the wrong location.
