Let’s check step-by-step:

1. Does your PC system meet the installation requirements?

√ I’ve installed Microsoft .NET Framework 3.5

× I do have .NET Framework, but it’s not 3.5 → Why do I still need .Net Framework 3.5 to run Octoparse? 


2. Is your anti-virus software blocking Octoparse?

√  No. My anti-virus software seems to get along well with Octoparse.

×  Yes. I got warnings from my anti-virus software. →  How to stop anti-virus software from blocking Octoparse? 


3. Do you have the Admin Right to the PC for Octoparse installation?

4. Are you connected to the Internet?

√  Yes.

×  No. Please check your Internet connection. Internet access is a must for Octoparse.


5. Are you in the region that gets banned from accessing to U.S. servers?
