Unexpected behaviour with Salesforce Dataloader v25


Salesforce have today notified it’s customers of a potential issue when uninstalling the latest version of the salesforce data loader (v25). The email below was distributed to it’s Premier Success customers providing details of the problem and possible solutions, including a link to our helpful data loader archive page! This issue is only present where version 25 has been installed outside of the default folder – for more details see the email below sent by salesforce.

We have observed unexpected behaviour with the salesforce version 25 Dataloader tool:

If this version is installed in a folder other than the default install folder it will delete all files located in that folder when the uninstall program is run.

As a workaround please user previous version 24 and older from this location -

as the usual data loader download page is being disabled.
We are working with our development team to resolve this issue as promptly as possible.
Additional information will be posted to as it becomes available.

Ensuring your success is our top priority at, and we are focused on solving this issue as well as preventing any recurrences. Thank you for continued business and your patience during this situation. – Premier Success Team

    Hello Guys..

    have likely behavior with the Salesforce Version 25 Data Loader tool
    that version 24 and 25 exhibit this behavior, they are update per a customer behavior.

    When the uninstall program is run for this Data Loader, it will
    delete the data loader installation directory.
    If additional files are manually saved in that directory, it will delete
    those files as well.
