hello
I have a problem opening zip files, and two months ago everything worked fine, I tried reinstalling snap many times to delete the GDAL folder, but none of this helped

Native library load failed (GDAL) when gpt called from a python subprocess - Optical Toolbox - STEP Forum (esa.int)
Maybe this discussion can help you
I do not use python while using snap, and I do not know how to install another version of gdal separately.
I have the very same problem with SNAP 10.0 and 11.0 and don’t know how to fix it.
I’ve also deleted the \.snap\auxdata\gdal folder but it always creates it again with gdal-3-7-2.
However, I can load my zip file with SNAP 9. In this case, an early version of GDAL is being installed. How can I manually downgrade GDAL for SNAP 10/11?
Dear Alexander,
The internal GDAL distribution cannot be downgraded. Please provide us with information about your OS version.
I’m using Windows 11 (64bit). Please find attached the full message log.

This issue might be related to a missing or corrupt Visual C++ Runtime.
Please check if Visual C++ Runtime 2017 is installed on your computer and try to repair/reinstall it.
I’ve reinstalled both Visual C++ Redistributables 2015-2022 (x86 and x64) but it didn’t solve the problem. It looks like I cannot install 2017 because the other redist is already installed.
Another thing I’ve realized: SNAP was working at first but stopped after upgrading QGIS. Maybe there is a connection!?
With QGIS 3.38.3 and SNAP 11 installed on Windows 11, we still cannot reproduce the error. We will continue the investigations.

Hi, I think I’ve encountered a similar issue. When updating the Snap (Windows) version to 10.0 or above, I’m getting an error saying it can’t find gdal-3-7-2, even though the path actually exists. I’ve taken some screenshots of the key error messages. Is this caused by the update in versions?
Hi Diana, do you have any updates on this or any idea what I could try to resolve the issue? Thanks, Alex
btw…here is the full error message stack
Hi Alexander,
Unfortunately, we still can’t reproduce the issue.
Could you check if the following environment variables are defined on your system and provide their values: GDAL_DRIVER_PATH, GDAL_PLUGINS, GDAL_DATA?
Could you also check if the PATH env. variable contains the path of an installed GDAL version?
Thank you!
Please close SNAP, replace your C:\Users\Admin\.snap\auxdata\gdal folder with the one downloaded from : https://step.esa.int/downloads/tmp20241113/gdal20241113.zip
and try to open a S2 product.
