After Upgrading, ControllerXLPusher Error Occurs When Starting Microsoft Excel

You accessed IBM® Controller at least once from the same client computer, and are now trying to start Microsoft Excel. An error message states that the ControllerXLPusher.dll file or one of its dependencies was not found. The registry may have more than one version listed for the ControllerXLPusher.dll file.

You must verify that the version used by the registry key is the current version of the ControllerXLPusher.dll file. First identify the current version of the ControllerXLPusher.dll file and then verify the version used by the registry key.

Procedure

  1. On the client computer, in the ccr_location\webcontent\ccr directory, right-click the ControllerXLPusher.dll file, and then click Properties.
  2. Click the Version tab and record the File version number for comparing against the registry key.
  3. Open the Registry Editor and search for ControllerXLPusher using the registry Find feature.

    The key HKEY_CLASSES_ROOT\CLSID\id_number should be found.

  4. Click the InprocServer32 key and check whether only the version number that matches the current version of the ControllerXLPusher.dll file exists.
  5. If more than one version exists, delete all entries except the current version, which you recorded earlier.
