tl;dr — If you’re getting a User Account Control prompt asking you to enter the administrator’s password for Paygistix, you have a bad install.
Paygistix is credit card processing software that resides on Windows-based computers in some consignment/resale stores. If you’ve just had Paygistix installed on your computer and it’s prompting you to enter the administrator password after you reboot, this means Paygistix was not properly installed and will need to be reinstalled.
This is a courtesy post for store owners out there who happen to still be on Paygistix and are encountering this issue. Unfortunately, this involves calling back to Payment Logistics to have them address the “bad” installation.
When all is said and done, you should be able to log-in to your non-administrator account after rebooting (e.g. the ‘Store’ user) and the Paygistix Client should run automatically, without prompting with a User Account Control password dialog.
