Compatibility of WinAC RTX on PCs with Single-Core Microprocessors

  • Entry
  • Associated product(s)

To be able to operate WinAC RTX 2005 or 2008 on Single-Core microprocessors without Hyperthreading or with Hyperthreading switched off, you require a "ACPI Uniprocessor" HAL to be able to completely install WinAC RTX.

Description

If you wish to install WinAC RTX on a Single-Core microprocessor with installed Multiprocessor HAL and running without Hyperthreading or with Hyperthreading switched off , WinAC RTX will abort installation with the error message "Unable to install RTX ... Runtime on this system ...". In this case you must first install a suitable "ACPI Uniprocessor PC" HAL before you can install WinAC RTX.

Correction

An FAQ is available for the current SIMATIC PCs

The description provided here for WinAC RTX 2005 is correspondingly valid for WinAC RTX 2008 with Ardence RTX V8.1.

For other PCs please proceed as follows:

  • Please check whether the "ACPI Uniprocessor" HAL is available on your PC. You will find the installed HAL type in the Windows Device Manager under "Computer".
  • Contact your PC manufacturer whether he can supply a matching ACPI Uniprocessor HAL or whether it is available on this system.
  • Install the Uniprocessor HAL according to the manufacturer’s instructions.
