Article by Rahul Achar updated February 15, 2023


If you are currently in the process of modifying your SOLIDWORKS installation to change its serial number, or maybe even add and remove certain products, you may run into the error “Source Folder Not Versioned Correctly” on the summary page: The source folder is not versioned properly.

Luckily, this problem has a fix. You don’t even need to exit the Installation Manager to implement it. Once you have applied the steps below, you can return to the window to complete the modification.

As the error message describes, you need to have the “” or “” file, which matches the version of the Installation Manager.

This file can be created from scratch, by following these steps:

  1. Navigate to the location specified by the error, and check if there already is a “” or “” present. If so, delete or rename it.
  2. Go to the View tab of your File Explorer and enable the “File Name Extensions” box in the Show/Hide section.

  3. Open NotePad from the Start Menu.
  4. In your new text document, type in the version of SOLIDWORKS which you are using, in the following format:

The header of your Installation Manager also shows the version and service pack, which you can use as a reference. Here are some examples:

  1. Save the file as “swdata99” in the location specified by the error.
  2. Rename the file extension from “swdata99.txt” to ‘”.
  3. Go back to your Installation Manager, hit “OK” on the error message and try clicking the “Modify” button again.

If you’ve completed the steps above correctly, the Installation Manager should proceed to the next stage. If you run into any further issues or another SOLIDWORKS installation error with the modification process, please contact your VAR.
