Glad it is working. A downside of the growing popularity of linux is the increased probability that the name chosen for a new program will be the same as the name used by some other package.

I deleted the snap and re-downloaded it but still faced the same problem. What should I do. can you help me?
Whyt’s the error message you get? What type of data do you try to open?
I’m trying to open a sentinel-2 image. But it won’t open. It doesn’t appear on the screen.
So, after using either the S2A_MSIL1C_*.zip file or the MTD_MSIL1C.xml in the *.SAFE folder or dragging the *SAFE folder onto the Product Tree in SNAP you a structure similar to this.
But if you then double-click on one of the bands nothing happens?
If so, please provide the log file.

Where have you downloaded the data?
I downloaded it from the USGS page. Unfortunately, I tried it again and nothing happened.

It seems that there is some issue with the modules for Sentinel-2. Probably the installation or the update process didn’t work well.
Pleas uninstall and install SNAP. Then it should work.
Hi again,
I have reinstalled and rebooted but still facing the same problem, I cannot open any files.
I am kind of stuck here.

Now it looks even worse.
Also, some of the snap core modules seem to be corrupted.
The update process seems to be very fragile on your system.
Can you delete the folder ‘C:\Users\THH\AppData\Roaming\SNAP’?
Afterwards, you should have a clean SNAP 8 installation without updates.
Try to open the images now.
If this works update, SNAP again.
You could also download the modules manually from
Index of /updatecenter/8.0 (esa.int)
The important folders are ‘snap’ and ‘snap-toolboxes’.
There are tools which can help you to download the files.
Afterwards you can install the downloaded files in the plugin-manager.
Before doing this. You could try if the update via the command line is more reliable for you.
Update SNAP from the command line - SNAP - Confluence (atlassian.net)
Thanks , I will try that. I have installed the plugins manually before- so I will try that again or as you suggest via cmd.
Hi again,
I can now open the images from the clean version- so that part seems to work fine, thank you!
to clarify:
The order to do things that you suggest is;
- delete the folder- done
- install snap- done
- update snap from the command line
- install plugins (either from snap or manually)
Best, Therese

The order of steps is correct.
You can actually skip the installation of SNAP. Once you have a working installation deleting this folder should bring you back to the initial state.
… and if you’re for a treat, here’s a very sweet one:
-
Trying to import 3 ALOS PALSAR full-pol images (from JAXA, CEOS format).
-
First file imported with no problem
-
Second file imported is the same as the first. Third file imported is the same as the first.
-
Ended up with the same three files opened in Product Explorer
… just when I thought I was going to be pleased with SNAP
(and no, I didn’t make a mistake, and no, the files are different)
@jun_lu Can you take a look at the Alos Palsar issue?
@jmbcarreiras please provide a screenshot with those 3 products. Also, it would be good to know which option you used for opening the products in SNAP: File → Open Product or File → Import?
Hi,
I used File > Import > SAR Sensors > ALOS PALSAR CEOS
I uninstalled SNAP and then installed it back again and now it’s all good.
Thanks

Hi again,
I uninstalled SNAP and installed it again so now it works and I can open my files. Thank you for the help!
I need to increase the java heap memory so I can run some prosesses and analyses but cannot find the snappy.ini file to change the java_max_mem: XG it in.
It is not under “C:\Program Files\snap\bin”, where can it be?
I cannot find it when I search either.

The file is in the snappy folder.
https://senbox.atlassian.net/wiki/spaces/SNAP/pages/1898053693/SNAP+FAQs#How-to-increase-memory-for-snappy%3F
Where this folder is located depends on how you have configured snappy.
For example it can be located in the site-packages folder of your environment.
e.g., C:\Users\Marco\anaconda3\envs\snap8_py35\Lib\site-packages\snappy
When you run snappy-conf you are asked where snappy shall be placed:
In your case it might be at <User_Dir>/.snap/snap-ypthon
Thank you,
I will keep on searching 
Hello sir
I receive this message : AppData\Roaming\SNAP\var\log folder.***
Please any idea
Hi,
can you provide more context?
What are you doing? Which command are you executing? What do you want to achieve?
