If the iPOS Payroll app has stopped working, make sure the following has been done:
Make sure you have ALL of your Windows updates, including any Optional updates that refer to the .NET Framework
Make sure you have a full exclusion on the c:\Program Files\iPOSPay (or for 64 bit systems, its C:\Program Files(x86)\iPOSPay) folder in your antivirus.
If your antivirus deleted any files from iPOS Payroll, you will need to reinstall iPOS Payroll. Use the links below to download and reinstall (note, you do not need to uninstall anything). If your antivirus exclusions are not in place, they can delete key files of our app. If you try reinstalling without modifying your antivirus, you will continue to have errors.
