Snap Error in opening zip file

[ABraun]

and did you test both SRTM 1Sec and 3Sec?

As reported here, re-installing SNAP 8 (including the deletion of user configuration data) fixes the error.

SNAP 8 freeze

Hello, in fact I used SRTM 1Sec HGT . 1- I used my old DEMs. 2- deleted the old once and let SNAP download automatically 3- I downloaded DEMs manually. But didn;t works Finally I decided to uninstall SNAP and re-install it again but with the first choice of DELETING old user data. and SNAP8 look it works good. Many thanks for you ABraun and all SNAP team.
