Log File Analyser FAQ

What happens when the licence expires?

When the licence expires, the Log File Analyser returns to the restricted free lite version. You will be able to open old projects, but you won't be able to add to them or create new projects.

Why can’t my Licence Key be saved?

The SEO Spider stores the licence in a file called licence.txt in the users home directory in a ‘.ScreamingFrogSEOSpider’ folder. You can see this location by going to Help->Debug and looking at the line labeled “Licence File”. Please check the following to resolve this issue:

  • Ensure you are able to create the licence file in the correct location.
  • If you are using a Mac, see the answer to this stackoverflow question.
  • If you are using Windows is could be the default user.home value supplied to Java is incorrect. Ideally your IT team should fix this. As a work around you can add: -Duser.home=DRIVE_LETTER:\path\to\writable\directory\ to the ScreamingFrogSEOSpider.l4j.ini file that controls memory settings.

What additional features does a licence provide?

A licence removes the 1,000 line log file limit and allows you to have multiple projects saved at a time. We also provide support for technical issues related to the Log File Analyser for licensed users. Licences are individual per user. If you have five members of the team who would like to use the licenced version, you will need five separate licences for each user.

How many users are permitted to use one licence?

Licences are individual per user. A single licence key is for a single authorised user. If you have five users using five copies of the Screaming Frog Log File Analyser software, you will require 5 separate licences. Please see section 3 of our terms and conditions for full details.

Can I use my licence on more than one device?

Yes. The licence allows you to install the Log File Analyser on multiple computers. Licences are individual per user. Please see section 3 of our terms and conditions for full details.

Why is my Licence Key saying it’s invalid?

If the Log File Analyser says your ‘licence key is invalid’, then please check the following, as the licence keys we provide always work.

Licence keys are displayed on screen when you check out, sent in an email with subject "Screaming Frog Log File Analyser licence details" and available at any time by logging into your account.

  • Ensure you are using the username we provided for your licence key, as this isn't always the same as your account username and it's not your email address. This is by far the most common issue we see
  • Copy and paste the username and licence key, they are not designed to be entered manually.
  • Please also double check you have inserted the provided ‘Username’ in the ‘Username’ field and the provided ‘Licence Key’, in the ‘Licence Key’ field.
  • You are entering a SEO Spider licence into the Log File Analyser.

Why do I get a blank screen?

If the Log File Analyser user interface isn't rendering for you then the chances are you've run into this Java bug. On our experience this seems to be an issue with Intel HD 5xx series graphics cards. We've had less of these recently, so it might be a drive update will help resolve this issue.

If not, please close the SEO Spider, then open up the following file in a text editor:

C:\Program Files (x86)\Screaming Frog Log File Analyser\ScreamingFrogLogFileAnalyser.l4j.ini

then add the following under the -Xmx line:


(You may have a permission issue here, so copying your desktop, editing, then copying back may be easier).

No when you start the Log File Analyser the user interface should render correctly.

Why do I get “error opening file for writing” when installing?

Try running the file as administrator by right clicking the installer and choosing “Run as administrator”. Alternatively log in to an administrator account. You may need to request assistance from your IT department depending on your company setup.

Why do I receive a 'protected your PC' message on installation in Windows 10?

When you install the Log File Analyser on Windows 10, you may receive a 'protected your PC' SmartScreen - Windows 10 SmartScreen To install, you have to click the 'More Info' link underneath and then 'Run Anyway' - smart screen more info link The reason for this is the certificate is new and it takes time for this message to disappear, despite being registered Windows developers.
