Just installed SNAP 8.0 64bit on my PC. On the initial boot, the updates are performed and installed. Once I drag and drop or try to open a sentiel-1 image, I get this problem :
A java.lang.IllegalStateException exception has occurred.
*** Click Show Details or see the messages.log file located in your C:\Users\LoanerOpti\AppData\Roaming\SNAP\var\log folder.***
I tried to locate the path, but AppData was not in said directory.
Windows File Explorer defaults are to hide the %USERPROFILE%\AppData folder. You can change this setting, but it is often more efficient to use a PowerShell terminal:
PS> cd $env:USERPROFILE\AppData\Roaming\SNAP\var\log
PS> more .\messages.log
Note that you can easily copy and paste text from a terminal to forum posts. Windows GUI tools are fine until something doesn’t work as expected, then you will find that learning some basic command-line procedures (starting with the above link) is well worth the time required.
