How it works

A Unit license is locked to a single computer or laptop. Once the license has been coded and sent, the license is bound to the computer for the term of the AMC contract. CDS uses FlexNET see About our Licensing

Troubleshooting unit 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
  
  
• 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.

Unit CDS.PWD license information

• Your CDS.PWD license file can be found in the \EPD x.x\ACAD sub-directory or use Windows>Search.
  
  
• You may view the CDS.PWD file with any ASCII text editor. Do not modify and re-save the file. If any changes are made to the original file and the file is re-saved, it will not work properly.
