If you have an InteractX HMI (EPX/HPX/IPX etc...) and it has the license in hardware bit InteractX has started coming up in One Hour Runtime mode this might help.
It is possible that this is an issue with Windows DLL files that are used by the runtime system to read the information from the license stored in hardware. This could happen after a power outage or any other instance where the hardware is power cycled without shutting down Windows first.
This could also be caused by a incomplete InteractX Runtime files install if the option to download InteractX runtime files was selected during a download and the uninstall and re-install of InteractX runtime did not complete successfully.
There are three DLL files that are required to read the hardware that can be damaged due to a "illegal" power down of Windows.
They are, memacc.dll, ntports.dll, and hmigatey.dll
If any are missing or damaged, the key will not be read. I checked with engineering and it should be possible to copy these files from a working system and just copy them over the top of the damaged ones.
They are located in the InteractX and subdirectories as follows:
File HMIGateKey.dll located at path: \Program Files (x86)\InteractX
File Memacc.dll located at path: \Program Files (x86)\MemAccess Library\Redist
File NTPort.dll located at path: \Program Files (x86)\NTPort Library\Redist
These files are not installed by InteractX, They are part of the Windows image installed on the different HMI platforms.
If you do not have the files, you can download the file below and extract it into a temporary folder to obtain the necessary files for your Parker HMI.
NOTE: This procedure does not work for hard drives that have completely failed and have a clean Windows install. This procedure only works if the files had been previously installed and registered in Windows. For a complete drive failure, the unit needs to be sent in for repair. Alternately, It might be possible to run InteractX versions 4.0 and higher with its' USB security key as with any Windows PC as long as the licensing core files are OK. Earlier InteractX versions could use a "soft" license that is stored on the hard drive.
