Cant open Sentinel 2 in SNAP 10 and in other versions

Optical Toolbox

Hello!

I read the forum threads. I have a problem with GDAL. Perhaps I need to replace GDAL.

Delete the folder and restart SNAP - does not work.

In any version of SNAP I do not have the GDAL Library Loader parameter.

In SNAP version 9 and older, Sentinel-2 toolbox is installed. In version 10 - Optical Toolbox. In older versions, sometimes old Sentinel-2 files (downloaded several months or years ago) can be opened.
Unfortunately, I do not know how to work in the Python environment.
OS - Windows 8.1 64-bit

Do you have the same issue with both SNAP 9 and SNAP 10? Can you check if, for the current version, all the updates are installed ? (Help → Check for Updates). For processing baseline 5.11(Sentinel 2 products after July 23, 2024), the latest updates are required.

For SNAP 9, are you using the internal GDAL distribution?

Diana, thanks for the answer!

I installed version 11. Unfortunately, all the problems remained. I can’t open the Sentinel-2 data, even the old data (downloaded in 2023).
I see that here (Errors opening S1 image in snap 9.0) there is the same problem

UP. I may have found the cause of the problem.

The path (C:\Users.….snap\auxdata\gdal) must be in English only!

Do you mean that it should not contain special characters?

I understood that there should be only Latin letters in the user profile on the computer. If the user name is in another language, then SNAP does not see the path to GDAL. Maybe special characters also affect.

Try creating a new user with a simple name in English. Then give administrator rights. Then install SNAP on behalf of this user.

That’s how SNAP started working for me.
