Trying to Open RAD Studio 7.0

I was trying to open a sample package in RAD Studio 7.0, but for some reason the following error pops out:

"Error
Can't load package C:UsersPublicDocumentsRAD
Studio7.0BplSamplePackage1.bpl.
The specified module could not be found.
Do you want to attempt to load this package the next
time a project is loaded?"
Does anybody know why I got this error and how can I solve it?
Thanks, Mark.
