Petro-SIM v7.1 and Windows 11 OS

In case of having issues installing Petro-SIM v7.1 on machines with Windows 11 OS, the following procedure is recommended to follow:

    1.	Open the Local Group Policy Editor. You can also search for gpedit.msc
    2.	Go to Computer Configuration -> Administrative Templates-> Windows Components-> Remote Desktop Services-> Remote Desktop Session Host-> Application Compatibility.
    3.	Right click on "Turn off Windows Installer RDS Compatibility" and click Edit.
    4.	Then select "Enabled" radio button (Not Configured is selected by default) and click on OK.
    5.	Rerun the installation.


If you still experience problems, please contact our Software Support team (software@kbc.global)


Help pages
Currently, we are experiencing technical difficulties with the Local Help pages, and we are working hard to resolve this issue quickly. As a workaround, if you are seeing a blank Help page, please click on either the Home button or Table of Contents button. Then, you can continue your search for topics under Help. The Web-based Help pages are working normally.


ISOM-SIM
Cases migrated to 7.1 (Build 2562) are unable to calibrate while using the integrated Calibration Optimizer in ISOM-SIM units (see “Refining Unit Operations --> Isomerization Reactor --> Calibration --> Calibration Tuning with Optimizer” in the Petro-SIM User Guide for information about using the integrated optimizer). This also applies to the “C5_C6 ISOM” sample case shipped with 7.1. New cases build via the wizard will function correctly. Any old cases can be sent into the Software Support Helpdesk (software@kbc.global) to be fixed up to work in 7.1. You can also request an updated “C5_C6 ISOM.ksc” sample case via the helpdesk. This bug has been fixed in 7.1 SP1 and above.


HXX-SIM

  • Migrated workbooks created before Petro-SIM V7.0 may have a bad dimension/unit of measure for Catalyst Density variables. If you see an error message relating to catalyst density being missing or omitted when running in V7.1, we recommend either generating a new workbook and migrating your data via XML export/import or manually editing the unit of measure for Catalyst Density parameters from "StdLiqMasDen" to "MassDensity". This second option is only recommended for users familiar with the KBC Excel Application ID system.
  • The validation of a DHTR-SIM object around polyaromatics prediction will fail if reactor effluent has less monoaromatics content than the feed stream. There is no workaround for this issue. If you run into this situation, please contact Software Support for evaluation and a potential hot fix. This bug has been fixed in 7.1 SP1 and above.
  • The "Cat. Par. Shape" variable (used only by the Pressure Drop feature) incorrectly treats an input of "Cylinder" as sphere and an input of "Sphere" as cylinder. The workaround for spherical catalyst is to input the shape as "Cylinder" and also input any positive number for the "Cat. Par. Length" (which will be ignored by the DP calculations) so that the reactor will not complain about a missing particle length. The workaround for cylindrical catalyst is to input the shape as "Sphere" but also input the "Cat. Par. Length" of the cylindrical particle and ignore any messages in the Trace Window that incorrectly claim "catalyst particle length is ignored". This bug has been fixed in V7.1 SP1 and above.


AMSIM in the 64-bit version
A major issue was found with AMSIM in the 64-bit version of Petro-SIM v7.1. To solve this problem the DBRAMINE64.dll shipped with Petro-SIM has to be replaced by following these instructions:

  1. Contact your Software Support representative at software@kbc.global and request the new DBRAMINE64.dll file.
  2. Open C: drive
  3. Go to Program Files --> KBC --> SIM Suite 7.1 -->Petro-SIM
  4. Rename the existing DBRAMINE64.dll (dated 2020-05-26)
  5. Save the new DBRAMINE64.dll (dated 2020-09-24) provided by Software Support

AMISM in v7.1 32-bits works properly and doesn’t require any fix.
