We have received reports of extraction errors on Windows with the large ZIP files that are used for the Symphobia Anniversary sale with Native Instruments. If this happens to you, please try using the free unzipping tool 7zip instead of your OS's standard unzipping tool.
If the actual download was successful, then 7zip should be able to extract the zip file correctly.
If the ZIP file extraction still fails, please re-download your purchase.
If the problem persists, please contact us for assistance.
