Has anyone gotten the Cisco Click to Call version 8 to work on Windows 7 x64 with Office 2010 64-bit?

I keep getting an issue in which the COM add-in does not start. I get error code "runtime error occurred"

Just to note that it is supported on your system:

Click to Call supports the 32-bit and 64-bit versions of the following operating systems:

·         Microsoft Windows XP Professional, Service Pack 2 or higher

·         Microsoft Windows Vista Business Edition or Enterprise Edition, Service Pack 2 or higher

·         Microsoft Windows 7 Professional Edition, Enterprise Edition, or Ultimate Edition

I would personally disable any antivirus and reinstall

Thanks for the reply, but I know it works on my OS, but I don't have it working on 64-Bit Office. My question really is has anyone gotten it to work on the 64-bit version of Office 2010?

I uninstalled 64-bit Office 2010 and installed the 32-bit version of Office 2010 and it works like a charm. I just really wanted to stick to running 64-bit.

I know that Internet Explorer 64-bit doesn't work either. I wonder if it's the same deal with Office 2010....

Thanks again.

  • Cisco Employee,


Not supported is the answer. Probably in the next release we may see the support but no official annoncement made yet.

reference link

C2C version: 8.0

Supported Desktop Applications

The following desktop applications can be used with the Click to Call application:

Mozilla Firefox 3.5 or higher

Microsoft Internet Explorer 7.0 and 8.0

Microsoft Excel 2003, 2007, and 20101

Microsoft Word 2003, 2007, and 20101

Microsoft Outlook 2003, 2007, and 20101

Microsoft Powerpoint 2003, 2007, and 20101

Theres a footnote to the above statement which states the following:

Hope it clarifies all doubts.

I suggest you point all of your customers toward their Cisco AMs to request it. The AM can attach customers to the enhancement request which should add pressure to the BU.

Microsoft recommend installing Office 2010 32-Bit on Windows 64-Bit

I'm not sure Cisco will ever release a 64-bit version. The same goes for most other vendors.

The recommendations for which edition of Office 2010 to install are as follows:

  • If users in your organization depend on existing extensions to  Office, such as ActiveX controls, third-party add-ins, in-house  solutions built on previous versions of Office, or 32-bit versions of  programs that interface directly with Office, we recommend that you  install 32-bit Office 2010 (the default installation) on computers that  are running both 32-bit and 64-bit supported Windows operating systems.

  • If some users in your organization are Excel expert users who  work with Excel spreadsheets that are larger than 2 gigabytes (GB), they  can install the 64-bit edition of Office 2010. In addition, if you have  in-house solution developers, we recommend that those developers have  access to the 64-bit edition of Office 2010 so that they can test and  update your in-house solutions on the 64-bit edition of Office 2010.

By default, Microsoft Office 2010 installs the 32-bit version of  Office 2010 even if your computer is running 64-bit editions of Windows.

Important    The 32-bit version of Office  2010 is the recommended option for most people, because it prevents  potential compatibility issues with other 32-bit applications,  specifically third-party add-ins that are available only for 32-bit  operating systems.

What is in the 32-bit version of Office but is not included in the 64-bit version of Office?

  • ActiveX controls library, ComCtl    This  library contains ActiveX controls that are used to build solutions. It  is most commonly used in the following Microsoft Office programs:  Access, Excel, and Word.
  • SharePoint List control    The list view in SharePoint Technology is not available to people using the 64-bit version of Office.

Compatibility with existing Office files and solutions

Note    The 64-bit version of Office 2010 is  not compatible with any other 32-bit version of Office programs. As a  result, you must first uninstall all 32-bit versions of Office programs  before you install the 64-bit version of Office 2010. The Office 2010  disc includes both 32- and 64-bit versions of Office 2010. To install  64-bit Office 2010, you must run Setup.exe from the x64 folder. For more  information, see Install the 64-bit version of Office.

  • ActiveX controls library, ComCtl    Any solutions that use these controls do not work. No good alternatives are available for some of these controls.
  • Third-party ActiveX controls and add-ins    None of these work with the 64-bit version of Office.

Note   There is no 64-bit version of Visual Basic 6. As a result, many of these objects need to be ported and rewritten.

  • Visual Basic for Applications    The only  way that Microsoft Visual Basic for Applications (VBA) that contains  the Declare statement work in the 64-bit version of Office is if you  update the code manually.
  • Compiled Access databases    The .MDE and  .ACCDE files, a common way for Access application developers to  distribute solutions and protect their intellectually property, do not  work in the 64-bit version of Office. You must contact the application  vendor to have the vendor recompile, retest, and redistribute the  solution in the 64-bit version.
  • Communicator integration    If you  install the 64-bit version of Office, certain Microsoft Office  Communicator 2007 features that involve integration with Outlook are  lost. For example, you cannot right-click a Communicator contact to  schedule a meeting, send an e-mail message, or find previous  conversations. This is because Office Communicator R2 is 32-bit, and  Messaging Application Programming Interface (MAPI) calls do not cross  the 32-/64-bit boundary.

Additionally, certain Microsoft Outlook 2010  features are unavailable with Communicator R2. For more information  about these Outlook features and the hotfix that addresses them, see the  following Knowledge Base article:
