when i try to download the additional installation package from help menu,it stops with 0% and shows this error.
Can you please clarify in which Talend version/edition you are? Is your network OK with you? Are you behind proxy or outof proxy?
More information will be helpful for us to address your issue.
Is there any more error information in your log?
We cannot repro this issue on window 10, v 7.0.1 from our side. What's OS are you using? Does this issue repro on other build version, v 6.5.1?
Could you please try to pause your Anti Virus to see if it works?
