Sage Exchange Desktop is required to add credit cards to the Sage Exchange Vault even if you are
not processing credit cards with Sage Payment Solutions. The record is placed in a Vault-Only when
adding a credit card to a customer in Accounts Receivable Customer Maintenance.
In some instances, the Sage Exchange Desktop will not properly install on one or more workstations.
In some cases, firewall and antivirus were found to be the cause.. In a few other cases where
it installs and works on some workstations, but not on others, the problem was a corrupted Windows
profile.
