Hello
I am trying to process a time series of S2 images between 2015-2016 with Sen2Cor 2.8. In some cases it works pretty much fine, but in others I get an strange error message:

I tried with a fresh output folder but the results are pretty much the same. Does anybody know what might be the source of this error?
In general to call the sen2cor from the console, you should add it your path, it seems that you didn’t add it,
I don’t know how it runs properly before as you said!
Add sen2cor to your path as below,
recall it by adding up the directory of your input,
L2A_Process.bat --resolution 20 --GIP_L2A /D:/S2.
Hello, thank you for your quick answer
I added the folder to the path as instructed, however, I am afraid I get the same message

I think you didn’t add the path as I mentioned in previous post, to be sure the path is added up correctly, aftermath typing
L2A_Process.bat --help
This should be the result,
Okay, this is weird. I did add the path, I checked. If I call the suggested command I get nothing… However, if I am running the cmd as administrator, it does produce the output you mention:
Basically you should unzip the file in C: then you’ll get this folder,
Delete the zip file, and then add up the path as you did, after adding up the path you could call the sen2cor from the console as I mentioned in the previous post,
For more details about the plugin, please take a look at the following thread,

It’s also explained under following item,
4.1New stand-alone installers(since release 2.4.0)

Also please take a look at following (Edit and add path in windows)

Hey @borlafgis,
I notice that you’re trying to process older sentinel-2 images (2015). Sen2Cor 2.8 doesn’t work well with older images from my personal experience. Try Sen2Cor 2.55 instead.
