Help: error updating of ScriptCase 7

Hi all, I’m new to ScriptCase 7.
when trying to update my ScriptCase 7 at the end, where the system finds all the updates to download and install, it throws an error message that says:
"Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at mymail@mymail.com to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log."

I thank you to help me, I can not update my ScriptCase

Hello,

This issue might be happening because your webserver cannot connect to ours webserver. Please make a manual update.

1 - Backup your SC
2 - Download SC ZIP or TGZ
3 - Extract SC ZIP on your previous SC installation
