Why do I get "Internet connection failed" when running the Java installer?

If you are having installation problems using online installation option, it's because your firewall or antivirus is locking EasyXLS installer when sending internet requests.

Another option that we are offering to you is partial online installation, using also the phone/email.

Prior to proceeding with offline installation, please send us an e-mail to support@easyxls.com, asking for "access codes". During installation you will need an access code used to access the Response Code screen on our website. When installing EasyXLS choose phone installation. Here are the steps that you must follow:


Enter personal information:
     - User Name: your name
     - Company Name: your company name
     - License key: the license key

Press "Next" button.

Customer information


Enter the requested information to certify yourself:
     - Certified Name: your name
     - Email: your email
     - Select the checkbox if you want to receive information on EasyXLS software products

Press "Next" button.

- If you have problems with Internet connection go to step Validate license key by phone.
- Otherwise continue to install
