How to troubleshoot problems when detecting a hardware key in Reliance

For protection, the Reliance SCADA/HMI system uses hardware keys by SafeNet (formerly Aladdin, now Gemalto). You can come across two types of keys:

  • HASP4

Go to the Reliance website's Download section to download and install the respective drivers for both types of keys (HASP4 – driver version 4.xx and HASP HL – driver version 5.xx and higher).

Note: Both driver versions are part of Reliance Add-On Pack (beginning with version 1.0.3).

Resolving the problem of hardware key detection

Beginning with version 4.0.14 (3.7.7), there's a different approach to hardware key drivers. If you come across a problem when upgrading to that version (or higher), we recommend that you follow these instructions:

1. Uninstall the existing drivers.

2. Install the current drivers for HASP HL (driver version 5.xx and higher).

If you fail to follow the instructions, download the driver version that allows you to install/uninstall drivers from a command prompt. The easiest way to do that is to download the drivers from this website's Download section or to use the drivers that are available in Reliance 4 Add-On Pack. The batches in these versions are ready to perform the basic operations of haspdinst.exe that is responsible for the installation itself.

Table of commands




Installation of HASP HL drivers


haspdinst.exe –i

Uninstallation of HASP HL drivers


haspdinst.exe –r -kp

Uninstallation of HASP HL and HASP4 drivers


haspdinst.exe –fr -kp

Once you extract the driver files from our website, run uninstall.bat. After uninstalling the drivers, reinstall them by running install.bat.

If you are still unable to detect your hardware key, run uninstallall.bat that will uninstall all types of HASP drivers (including HASP4).
