Hardware: Switchable Graphics AutoCAD resolution error.

This is about the new "Switchable Graphics" systems… more to this below.

This can cause display and/or resolution issues when running AutoCAD, maybe other products are affected too.

Basically, what it does in the background, it automatically switches from the current adapter to another and vice versa, to extend the battery life.

So when starting AutoCAD the following message appears, even though the current resolution setting is higher than the minimum requirements for AutoCAD.

Note there are no certified Autodesk drivers available for this setup.

However, there are some tweaks that can be performed to get around it (depending on the used system).

  1. Refer to the vendor's manual for possible settings.
  2. Ensure that the currently used adapter has the correct resolution and DPI settings.
  3. Make sure that 3D applications are setup to use the GPU rather than the integrated graphic adapter.

    In some driver settings you can choose what adapter to be used for which application. See screenshots below.


However, on some systems you need to perform this settings manually and setup the correct screen to be used and the desired resolution and dpi settings.

This can be performed in the OS display properties. (Settings may very).

In some instances it is recommended to refer to this driver.

What worked for us is to match both adapter settings (so GPU and integrated graphics have the same resolution and DPI settings).

This should help to resolve this instance and next time AutoCAD starts the appearance should be fine.

Thanks to Martin Langolf @Autodesk for this post.

General Licensing: hostid is ffffffff and a -97, 121 error

Here is the same -97,121 error but this time, it was on a highend server.  It was configured with a 4 port HP NC382i Integrated Dual Port PCI Express Gigabit Server Adapter.

This was the result of an ipconfig -all on the server:

Ethernet adapter Local Area Connection 4:
Description . . . . . . . . . . . : Microsoft Virtual Network Switch Adapter #4
Physical Address. . . . . . . . . : 00-26-55-4C-XX-XX

Ethernet adapter Local Area Connection 3:
Description . . . . . . . . . . . : Microsoft Virtual Network Switch Adapter #3
Physical Address. . . . . . . . . : 00-26-55-4C-XX-XX

Ethernet adapter Local Area Connection 2:
Description . . . . . . . . . . . : Microsoft Virtual Network Switch Adapter #2

Ethernet adapter Lan 1:
Description . . . . . . . . . . . : HP NC382i DP Multifunction Gigabit Server Adapter #51
Physical Address. . . . . . . . . : 00-26-55-4C-XX-XX

This was the result checking the status of the lmtools.exe, right after a reboot of the license server.

Itab LMtools

The interesting behaviour is that it worked when you initially started the license server.  When the system rebooted, the server would stop and the error in the log file would be:

12:18:29 (adskflex) SERVER line says 0026554cXXXX, hostid is ffffffff

You would need to Start the license server in lmtools and it would be working as expected.


The solution is below:

"...[because] the software complained about a wrong ID when the server restarted, but not when I manually ReRead the license file, I thought maybe the Autodesk service started too soon. So I changed the Startup to Automatic (Delayed) and it actually....worked!"   Axel H. Isegg

Product Keys: Getting your product key from the compressed downloaded file via Subcenter

Here is an awesome tip, if you have downloaded your software via the Subscription Center, just before you extract the file, you can extrapolate the product key from the part number.  Here are some samples:

AutoCAD 2011


Mudbox 2012



If you are using a Multiflex license, you can use the Multiflex Product Key [535D1] for any of the 2012 products.   If you plan to use a 2011 product, use the 2012 serial number and then use the default 2011 product key.

For example, if you have the Product Design Suite 2012 on Subscription, you will be able to run the older products.  

1. Download the 2011/2010/2009 from the Subscription Center.

2. Extract the file and note the Product Key.

3. Install the software using the 2012 serial number but use the product key noted in step #2.

Revit 2012: Installing Extensions as part of a deployment

In order to installl your extensions as part of a deployment, you will need to perform the following steps:

1.  Create a network deployment for your Revit 2012 product.

2.  Under the AdminImage folder create a new folder called: Extensions.

3.  Copy the MSI files for the Revit Extensions like DBLink and Worksharing Monitor to the Extensions folder.

4.  Edit the deployment ini file and add the following to the very bottom

#================ REVIT Extensions ================



PRODUCT_NAME=Autodesk Revit 2012 DBLink




PRODUCT_NAME=Autodesk Revit 2012 Batch Printing




PRODUCT_NAME=Autodesk Revit 2012 Worksharing Monitor


Still in the deployment ini file, scroll back up near the top under the Revit section and modify the following line adding the three sections at the end using the same names from the Revit Extensions section already added.


Now save the ini and try installing the deployment to a client workstation, this will install Revit and the extensions without prompting the user, and should work when pushed to the clients using something like SCCM (will not work with GPO pushes). This will not work with the REX Extensions as they install through their own Setup.exe and we can only run one Setup.exe at a time.

adskflex: The desired vendor daemon is down. FLEXnet Licensing error:-97,121

We notice several users having this error appearing in the "Perform Status Enquiry" result text, when the Network License Manager is not working.

This error is definitely due to the usage of an old version of the Network License Manager which doesn't recognize the newest license file formats.

To solve this problem, just upgrade the Network License Manager to the latest version available.

The latest version available for the Autodesk Network License Manager is available here: Latest Version of the Autodesk Network License Manager

AutoCAD Civil 3D 2012: Unhandled Exception E0434352 (e0434352h) at address 7C812AFBh

We recently had an case in Product Support in which AutoCAD Civil 3D 2012 [Standalone] & ArcGIS 10 [Standalone] installed on a Windows XP SP3 [32bit] computer will produce the following error:

Craig Geren-civil2012-error

Unhandled Exception E0434352 (e0434352h) at address 7C812AFBh

As soon as ArcGIS is uninstalled, AutoCAD Civil 3D 2012 will function properly.

When you try to reset AutoCAD Civil 3D by initializing the secondary installer, the user interface will come up but it will still have the unhandled exception error.  AutoCAD Civil 3D 2012 will be usable after you click "OK".

Craig Geren-civil2012-error2

To resolve this error, backup, then edit the following file using Notepad:

C:\Program Files\Autodesk\AutoCAD Civil 3D 2012\Acad.exe.Config

<startup useLegacyV2RuntimeActivationPolicy="false">
<supportedRuntime version="v4.0"/>

I have included the default settings of this file here:  Acad.exe.config


I would like to thank Craig Geren for sharing this tip with the community.

General Licensing: FLEXnet Licensing error:-125,147

I have received several cases on this interesting error message in lmtools.exe.  You will only get this error when you go here:

lmtools.exe > Server Diags > Perform Diagnostics

When you look in the status window, one of the error messages will be:

FLEXnet Licensing error:-125,147

Typically, I always use this tab to check the server status:

lmtools.exe > Server Status > Perform Status Inquiry

Basically, this is an error that can be safely ignored!   I have included a video to show you that the status of the server and the various UI elements in this tool.

Video:    Setup-lmtools-and-125-error

You can choose to Edit > Clear Window to clear out the messages in the status window.
