When I run a sync with between my mobile device and Outlook 97 I get this error message. I have reinstalled PDAsync but I still get the message. What can I do?


A defect exists in PDAsync version 1.0 and 1.33.


Contact LapLink Technical Support to receive a free update that solves this problem. This workaround works in some situations, but not all.

  1. See Technical Document 668: How do I Ensure that PDAsync is Completely Uninstalled? for steps to remove the current version of PDAsync.
  2. Use Windows Search (or Find) to locate all copies of the file CDO.DLL.
  3. In the Search results window, make sure that the file is in the \ Windows\System folder. Copy the file to this location if necessary.
  4. Reinstall PDAsync and try the sync again.
  5. If it still fails, go to a Command Prompt (aka DOS prompt) and type the following command
  6. regsvr32 C:\WINNT\System32\CDO.DLL
  7. When you see DllRegisterServer in C:\WINNT\System32\CDO.dll succeeded, type Exit.
  8. Try PDAsync again.
Note: This file is required by Outlook and these older versions of PDAsync, however, it is not distributed with Outlook 97. If the file is missing from your computer, contact Microsoft Technical Support for possible solutions, or wait for the update to PDAsync to arrive.
