  • Question:How Do I Activate My Software?

    Answer :

    Once you fill in your name and a valid serial number, the “Activate Later”, “Activate over the Internet” and “Activate by Phone/Fax/Email” buttons will go from grayed out to active. If for some reason, you choose not to Activate now, you can choose the Activate Later button and the installation will continue. However, each time you launch one of the programs installed, you will see this prompt, which means entering your name and serial number each time.

    If you are connected to the Internet, and have no firewalls running, you can choose the “Activate over Internet” button. If you have any problems with Activate over Internet, use the Activate by Phone/Fax/Email instead.

  • Question:During The Installation, I Get An Error That The Serial Number Or Registration Code Is Invalid?

    Answer :

    If you are only putting in a serial number and not the registration code, then you would see this error. Both codes can be found on the ReadMe First card that came in the box. You must enter each in the corresponding fields during the installation.

  • Question:I Installed Chemdraw Ultra 6.0, But When I Launch, Chemdraw, Chem3d And Chemfinder, It Asks Me For The Codes. The Codes Only Work With Chemdraw And Not With Chem3d And Chemfinder?

    Answer :

    You should never be prompted for codes when launching an application. You should only be prompted for the codes during the installation. The codes are only meant to work at installation of the ChemDraw Ultra suite. The Chem3D and ChemFinder applications that come with ChemDraw Ultra are version 5.0, where the ChemDraw application is 6.0. The codes are 6.0 codes, so they will only work with ChemDraw at start up. Try uninstalling the software using the Add/Remove Programs control panel, make sure you are logged on as an Administrator to the machine, then reinstall the software and retest the applications while logged on as Administrator.

  • Question:I Am Being Prompted For Codes, But The Registration Code I Have Does Not Fit In The Space Provided Or I Get A Message Stating That The Codes Are Not Correct?

    Answer :

    First, you should only be prompted for codes during the installation of the software, not when launching. If you are being prompted for codes when launching, then there was a problem with the installation. Try uninstalling and reinstalling our software. Make sure you install and launch with sufficient access privileges.

    If the reg code does not fit or you get an error that they do not match during the installation, then most likely you are using codes not appopriate for the installer. Check to make sure that the cd-rom label matches the the description and version for the codes you have. The sticker the codes came on should indicate the product and version.

  • Question:When I Launch The Software, I Always Get Prompted For Codes. It Never Remembers Them?

    Answer :

    Make sure you have full write access to the location you have installed the software to, as well as the C Drive. If you do not have full write access during installation, this problem will occur. You will either need temporary full access privileges or you will need to have a network administrator install the software for you.

Once we receive your request, we will examine your activation history, and your reason for more activations and decide if you are eligible for an increase in activations.

  • Question:When I Launch The Software, I Get An Error That The License Has Expired?

    You may have installed our trial software at some point, which is set to expire after 2 weeks. Go to the Add/Remove Programs Control Panel. Look for any CambridgeSoft software and uninstall it.

  • Question:When I Double Click On A Structure Pasted Into A Word 6 Or Above Document, The Chemdraw Tools Do Not Launch For Editing The Structure?

    Answer :

    EGO was the protocol used that would allow you to edit structures within the Word 5.x document. Microsoft has dropped support of EGO in Word 6 and above. Word 6 and above support a graphic linking protocol called OLE. We would like to support OLE in a future version of ChemDraw for the Mac, but Microsoft does not appear to support Macintosh OLE development any longer.

    Therefore, you will need to copy and paste between ChemDraw Mac and Word 6.x. We also suggest contacting Microsoft about dropping EGO which most other word processors still support.

  • Question:When I Flip A Structure, The Absolute Stereochemistry Is Not Preserved?

    Answer :

    ChemDraw is behaving as designed. The flip command is designed to be graphical, so it is flipping the structure. If you want to preserve the stereochemistry, use the “Rotate 180 degrees Horizontal” or “Rotate 180 degrees Vertical” option in the Object menu.

    In versions of ChemDraw prior to 9.0, select the structure, hold own the Alt key, then click (and hold) on the Object menu. Now instead of “Flip Horizontal” or “Flip Vertical” it should say “Rotate 180 degrees Horizontal” and “Rotate 180 degrees Vertical”.

  • Question:I Need To Be Able To Create Customized Labels For R-groups For Analysis In Excel?

    Answer :

    There is a way for you to add more structures that can be recognized by the Excel Add-in during an R-Group Analysis. Basically, you need to create the corresponding structures in the Nicknames folder.

    In Windows XP, this folder is located by default under: C:Documents and SettingsAll UsersApplication DataCambridgeSoftChemOffice2010ChemDrawChemDraw ItemsNicknames

    If you have Windows Vista or 7, the ChemDraw nicknames structures folder is under: C:ProgramDataCambridgeSoftChemOffice2010ChemDrawChemDraw ItemsNicknames

    You can use existing .cdxml files on that folder as a starting point (i.e.: Phenyl.cdxml) to add more structures that can be recognized by the Excel Add-in during an R-Group Analysis.
