fail to install package

Hi,

When I try to install a package (quip), I get the following error:
Attempting to install package with signature: quip-2.0.0-rc1
Package found...now preparing to install.
Target directory is either not a directory or writable: C:/wamp/www/core/packages/
Could not transfer package quip-2.0.0-rc1.transport.zip to C:/wamp/www/core/packages/.
Could not install package with signature: quip-2.0.0-rc1

Modx wants to transfer the package to C:/wamp/www/core/packages/, but this directory doesn’t exist. It should be C:/wamp/www/mysite/core/packages/.
How is this path rendered? Can I manually change it?

Thanks.

If you moved your site from the root location to mysite/ you’ll need to follow the instructions for moving your site or re-run setup in upgrade mode in the new location.

Thanks for the quick reply. I reinstalled the site and it works now.
The strange thing is I’ve never moved my site, but who cares
