1. “This installation package is not supported by this processor type. Contact your product vendor.”

CHECKPOLE has been optimised for 64-bit operating systems to prevent memory issues when analysing resource-intensive map image data.

2. Why can’t activate my licence?

CHECKPOLE requires an active internet connection to validate licence credentials and manage users. If you are behind a firewall or proxy, you may have trouble connecting to the Revolutio licence server. In such cases, you have some options:

  • Allow CHECKPOLE to access the internet through your firewall.
  • Open standard HTTP (80) and HTTPS (443) ports.
  • Allow access to and domains.
  • CHECKPOLE will display a notification warning if it detects a proxy; you can edit the proxy settings by clicking on the notification.

3. How can I solve the “Unable to generate machine fingerprint error”?

This is a problem with the Windows Management Instrumentation (WMI). One of the following options may help to resolve this issue. We recommend that you speak with your IT support before attempting.


  1. Run cmd as Administrator.
  2. Type “cd wbem” and press Enter.
  3. Type “dir /b *.mof *.mfl | findstr /v /i uninstall > moflist.txt & for /F %s in (moflist.txt) do mofcomp %s” and press Enter.


Follow the instructions from Microsoft:


  1. Run cmd as Administrator.
  2. Type “net stop winmgmt” and press Enter.
  3. Open a Windows Explorer and locate the path to C: windowssystem32WBEM folder and rename the “Repository” folder to something else like “RepositoryOLD” (right-click and choose “Rename Folder”).
  4. Restart the computer.
  5. Run cmd as Administrator.
  6. Type “net stop winmgmt” and press Enter.
  7. Type “winmgmt /resetRepository” and restart the computer.

4. Why do the map tiles have the message “Exception: The remote server returned an error: (403) Forbidden.”?

CHECKPOLE uses Firefox as the user agent for accessing Google Maps data. Please ensure this is not blocked/filtered with your network security settings.

5. Why do the map tiles have the message “We are sorry, but we don’t have imagery at this zoom level for this region.”?

You will need to configure your network settings, proxy and/or firewall to allow CHECKPOLE access to Google Maps.

6. Why is the terrain/exposure category detection not always totally accurate?

We’re dependent on the quality of Google Maps data for terrain/exposure category detection. Most new structures are built in or near urban areas where map data tends to be more accurate, and for this reason the detection algorithm is catered towards getting the best possible answers for urban sites.

Regional sites may have less refined map data, leading the detection algorithm to provide less accurate results. However, their isolation usually makes determining the terrain/exposure category straightforward by simply reviewing the satellite imagery. It’s for this reason that we overlay the influence zones on the map to allow the user to confirm that the detected terrain/exposure categories make sense.

7. Why is the natural frequency calculated by CHECKPOLE different to that calculated by my structural analysis software?

CHECKPOLE uses the Rayleigh method to calculate the first mode natural frequency. The advantage of the Rayleigh method is that it enables CHECKPOLE to account the mass of lap joints, stiffness reductions at openings, non-uniform shaft mass from tapers and masses above the tip, which is otherwise more difficult using a conventional stiffness formulation.

If the natural frequency for a library pole calculated by CHECKPOLE is lower than you’ve calculated in a program such as SPACE GASS, that makes perfect sense; CHECKPOLE is taking into account the mass of material at the laps and also any openings along its length which will drastically reduce stiffness, neither of which can are considered by programs such as Mstower or SPACE GASS.

8. How are the capacity of openings calculated?

Cross-sections with openings are calculated as per EN 40-3-3, incorporating relevant capacity reduction factors of selected design reference. EN 40-3-3 is based on experimental testing of single openings in street light poles and considers both plate and member buckling effects.

9. If CHECKPOLE compatible with tnxTower?

Yes! CHECKPOLE has a import feature that allows you to import both tower analysis (.eri) and all associated library (.arc) files automatically. Because CHECKPOLE offers a much more comprehensive analysis of monopoles, you may have to fill in some of the gaps (i.e. openings, connections, etc) after importing. You can also send us your tnxTower files for us to do this conversion for you at no cost.

10. Can you explain the different options for the Topography Dataset in the Settings menu?

The availability of specific, accurate, and portable topographic data is an extremely complex issue. We have to attempted to simplify matters by referencing multiple datasets and also providing users with alternative options to best serve their needs.

The “DEFAULT” option samples multiple high resolution topography datasets from GPXZ based on the site coordinates to find the best available data for that location. This is the recommended option for vast majority of users.

The “GOOGLE” option uses Google’s Elevation API as per legacy versions of CHECKPOLE.
