Access to data problem after v23 upgrade

We're having a problem upgrading to v23. v23 is successfully installed on one of 2 PCs, the one holding the data. The share is still in place to access the data across the network. The copy of Sage on the 2nd PC says it cannot access the data on this share. The help says to install v23 on the 2nd PC. The option is not available, grayed out. Only v21 and v22. Is there a "full-file" download of v23 that would work? Any other suggestions?
