The installation source for this product is not available

I get this 102 error when using the computer configuration > software settings > software installation > through group policy. The computer is within the OU that the policy applies.  This .msi is in a folder which is shared so that everyone can access it. Any ideas?  I also get the following errors after event id 102:
