CAD Design Software - Hardware Key License Support


NOTICE: As of 2015, USB Dongle Keys are no longer sold or supported


License Key Policy:  

bullet A damaged Dongle Key will NOT be replaced, must convert to single computer license (UNIT-based).  
bullet Hardware keys (dongles) are for USA use only and may not be taken out, sold/shipped or used outside of the USA.
bullet Dongle Keys may be used for UNIT-based license only. Hardware Dongle Keys cannot be used or sold for Network (server) based licensing.

bullet There will be no replacement for a Dongle Key that has been lost, stolen, etc.  A single 1 year license will be issued annually as a UNIT-based / single computer use license.

How it works:

bullet Very Important!! • Do not plug the dongle into your machine before installing the dongle driver. Plugging in the dongle can cause an automatic search for driver files. The driver files found by an automatic search might not be compatible with FlexNet ID dongle.


When moving the hardware key to another workstation loaded with CAD Design Software, use the CDS.PWD file that was issued. 

  • Match the CDS.PWD with the hardware key
  • Open the CDS.PWD with Notepad 
  • Locate the HOSTID=FLEXID= line
  • Look on the face of the key FLEXID=
  • Match the key with the PWD
  • You can leave the CDS.PWD on the workstation(s)

Download and Install the Dongle Key Drivers


bullet Very Important!! • Do not plug the dongle into your machine before installing the dongle driver. Plugging in the dongle can cause an automatic search for driver files. The driver files found by an automatic search might not be compatible with FlexNet ID dongle.


  • On a Windows 64-bit machine, only one Aladdin HASP dongle is detected even when multiple dongles are attached to the machine. This is a known limitation of the HASP HL APIs that are used by the FlexNet licensing software.

  • The Aladdin HASP dongle does not support Remote Desktop Connection for applications built with Windows 32-bit toolkits. This is a known limitation of the HASP APIs that are used by the FlexNet licensing software.

Download and Install:

Download ZIP file WINDOWS 7, 8 :

Download ZIP file WINDOWS 10 / AutoCAD 2017, 2018 : 
1. Open ZIP file which will contain:
1b. FLEXIDxx_i686.ZIP (32 bit CPU)
1c. FLEXIDxx_x64.ZIP (64 bit CPU)
1d. haspsrm_win32.dll
1e. haspsrm_win64.dll
2. Now Open the applicable FLEXIDxxx_xxx.ZIP file for the CPU Bit-type which will contain:
2a. haspdinst.exe
3. On 64-bit Windows systems, copy the haspsrm_win32.dll file to %windir%/System32 (typically C:\Windows\System32) and then and copy the haspsrm_win64.dll file to %windir%/SysWOW64 (typically C:\Windows\SysWOW64)
On 32-bit Windows systems, copy the haspsrm_win32.dll file to %windir%/System32 (typically C:\Windows\System32).
4. Copy the haspdinst.exe to a 'new directory' for use in a DOS command prompt window.

4a. for example: Create a folder called C:\haspinstall and place the haspdinst.exe in it.
5. Open a DOS window (Start>Run>CMD) and then set current directory to the new folder

5a. for example: Type... cd c:\haspinstall and then press <Enter> so current folder is at prompt

6. Once set to the correct folder/directory where the dongle-driver installer resides, type... haspdinst.exe -i and then press <Enter>.

7. Next when install is done >Restart the computer<  but.. Do not Insert Key yet!!
After installation and a computer restart, > Insert the USB dongle key into a free USB slot of the computer. Windows will “Find new hardware” and then install the drivers, etc.

  • CAD Design Software will issue the user a license file that is coded to the dongle key’s serial number. 

  • This file is named CDS.PWD (license may have been sent with file name of the dongle serial number, just rename to cds.pwd) Keep a copy of this file in a safe place. 

  • The CDS.PWD file must be placed in the C:\CAD Design Software\EPD 8.2\Acad sub-directory of the CAD Design Software product installation directory.

Troubleshooting dongle license
  • VERIFY that there are no duplicate CDS.PWD files on the system.

  • VERIFY that the CDS.PWD file is stored in the \software\ACAD\ sub-directory.

  • VERIFY that the CDS.PWD file does not have a double file extension (i.e.  CDS.PWD.PWD)

  • VERIFY you are using the correct CDS.PWD that relates to the serial number on the key (See Above)

  • System clock has been set back -VERIFY that system clock is set to the proper date and time. A system file has been changed so it is 24 hours or more in advance. This will cause a security error with the license program. It assumes that the user has modified the system clock to avoid a "Time-Lock" license. This might be a system error or accidentally done by the user. First step is to check the BIOS clock settings. In most cases, this will resolve the problem. Refer to your motherboard user manual for information on BIOS settings. 

  • If you get an error message that reads: The hostid of this system does not match the hostid specified in the license file. This error means that the computer cannot find the hardware (dongle key). The most common reason is the drivers were not installed correctly by the Windows Operating System. Possible reasons could be that there are securities preventing the installation of the hardware drivers, user does not have full rights or the key is not recognized because it is plugged into a USB port that does not properly respond.
  • Install the driver files before plugging the dongle in to your machine.
  • Do not allow Windows Update to install later versions of the dongle drivers. Such an update leads to
    unpredictable behavior of the dongles with FlexNet licensing software.
  • The dongle driver cannot be removed using FLEXID_Dongle_Driver_Installer.exe.

Flex ID Driver Clean-Up

If existing dongle drivers were installed using the older installer FLEXIdInstaller.exe rather than the current installer, you may use the cleanup utility FLEXidCleanUtility.exe to uninstall them.

Alternatively, you may use the Add or Remove Programs from the Control Panel to accomplish this.

If existing drivers were installed using the installer FLEXId_Dongle_Driver_Installer.exe, then this cleanup utility is not needed.

  1. Remove the hardware key from the computer.

  2. Use the Add/Remove Programs in the Windows Control Panel and remove the 'Macrovision FLEXid Drivers' or 'Sentinel System Driver'

  3. Download the Clean Up Utility (Download)

  4. Run the EXE and follow the prompts to remove the drivers.

  5. Restart the Computer

  6. Download this new Set of Drivers (See the Download Section) and restart the computer

  7. Plug in the key

  8. Run the software
