What you install
AI Zeny for Windows

Windows services
The services the app runs with, added by the installer.
.NET runtime
The runtime the app needs, included in the installer.
Before you run the installer
Unsigned installer
The installer is not code-signed, so Windows shows it as coming from an unknown publisher and may warn you before it runs. The installation guide shows the warning and what to choose.
If Windows warns you, choose:
More infothenRun anyway
Updates itself
The app updates itself automatically and checks each update’s integrity before installing it. That check is separate from code signing and does not change the Windows publisher warning.
Trouble connecting to Microsoft Access?
Missing 64-bit Access driver
If your BUSY company uses Microsoft Access and AI Zeny reports a missing driver or Access Database Engine error, check your Office setup and install the compatible Runtime.
