2249958 - Unable to add the SAP Business Warehouse Data Acquisition Connector extension in Lumira Desktop


When attempting to add the Data Acquisition Extension: "Download data from SAP Business Warehouse" in Lumira, it displays the message:

Error message: The extension folder 'bundles' could not be accessed


  • SAP BusinessObjects Lumira Desktop

Reproducing the Issue

  • Open Lumira
  • Select 'File' => Extension=> click on install for any extension and you get this error :

'Error message: The extension folder 'bundles' could not be accessed'



  • User rights related issue
  • Network connectivity
  • Corrupted folders


First, take a look at, and understand where the workflow fails; steps below represent the expected behaviour:

Remove extensions folder (if exists) and start Lumira - initial state:



If its empty, the extension hasn't been downloaded or has been removed. Go to Extensions:


Install the extension:


Check the folder again:


The 'sap' folder should be present.

  • If 'sap' folder appeared, the extension has been installed properly. Inability to access it suggests application rights issue with Lumira and/or the user being unable to read it.
  • If 'sap' folder doesn't exist, it means that the directory is either inaccessible to Lumira application and/or user, or rights are missing.

To narrow down the root cause:

  1. Check Event Viewer logs on that machine – if it is rights related its very likely that it will be flagged there
  2. If that doesn’t show anything, use process monitor to see where the wall is, and address it
