Overcoming Installation Problems
Managing Serial Ports and USB ports
- Make sure your anti-malware applications (firewall, anti-virus) applications are considered "safe"
- failure to do this can result in long startup delays

If the printer selected on DXKeeper's QSL Configuration window's Printer tab is not local, make sure the printer is accessible; otherwise, DXKeeper's startup time may be significantly increased.

Booting Windows into Safe Mode with Networking
One way to determine whether applications or services being automatically started by Windows is to boot (restart) Windows into Safe Mode with Networking. In this mode, only basic device drivers are loaded, and no applications or services are automatically started. Serial ports and USB devices won't be operational, but a DXLab application that starts up promptly in Safe Mode with Networking but takes much longer to start up when Windows has been booted normally indicates that one of the applications or services by automatically started by Windows is responsible for the behavior.
To boot Windows 2000, NT, Vista, XP, 7, or 8 into Safe Mode with Networking, follow these instructions
To boot Windows 10 into Safe Mode with Networking, follow these instructions
Controlling Windows and Anti-Malware Updates
Configure Windows and Anti-Malware applications to automatically download updates, but to not automatically install them. When you see that updates are available, direct Windows to create a restore point. After installing the updates, verify that your DXLab applications continue to work correctly. If there's a problem and you're using Windows 10, follow these instructions to revert to the previous version; on other flavors of Windows, revert to the restore point you created.
Out of the box, Windows 10 cannot be stopped from downloading and installing updates.
