Using the ArcPad ECW Extension on Windows 7

ECW (Enhanced Compression Wavelet) is a proprietary wavelet compression image format optimized for aerial and satellite imagery. The lossy compression format efficiently compresses very large images with fine alternating contrast.

Support for ECW files in ArcPad has been available as of ArcPad 6 with the addition of a the ECW Extension for ArcPad.

The ECW Extension for ArcPad is available (at no cost) from Intergraph/Erdas at the following website:

This version of the ECW Extension for ArcPad will work with all subsequent versions of ArcPad.

HOWEVER: Some users have been running into issues when attempting to use this extension on versions of Windows other than XP (which is what is was originally developed against).

The following instructions will allow you to install the extension on a Windows 7 PC:

  1.    Type ‘compat’ into the Start Menu search and select ‘Run Programs made for previous versions of Windows’
  2.    Click ‘Next’ on the Program Compatability wizard
  3.    Select ‘ArcPad’ from the list of programs and then click ‘Next’
  4.    Select ‘Troubleshoot Program’ as your troubleshooting option
  5.    Check the ‘I don’t see my problem listed’ option and then click ‘Next’
  6.    Select ‘I don’t know’ from the list of Windows versions and then click ‘Next’
  7.    Check the ‘I don’t see my problem listed’ option and then click ‘Next’
  8.    Click ‘Start the Program’ to launch ArcPad (enter license code if prompted)
  10.    Run the ArcPad_6.0_ECW_Plugin_v1.2.exe
  11.    Check that the install is successful by loading a .ecw file into ArcPad
  12.    Click ‘Next’ on the Program Compatability wizard
  13.    Select ‘Yes, save these settings for this program’ to finish

Now you should be able to use the ECW Extension for ArcPad on a Windows 7 PC!

    I have had no problems getting the ECW Plug-in to install under Windows 7 32 bit for ArcPad 10, however have had no luck under Windows 7 64 bit. The InstallShield Wizard just hangs. Any one out there had any luck.

    Anyone have luck with ArcPad 10.1? I am having no luck with any of the CAB files. They install, and I can see images, but that is it. I cannot zoom, pan, etc. I have tried all CAB's (PPC ARM, HPC_2000 ARM, PPC 2002 ARM)<--Don't really know which one is correct for my Trimble GeoXH. Any advice??

    Hi All, I noticed that the link in this original post is no longer valid. To download go to
    and choose to show legacy downloads.
    Similar to the sentiments in the above comments, i cant even find the cabs to try and install on Windows Mobile, however the readme.txt does specifically state that it was built for Windows CE 2.11, 2.12, and 3.0 (Pocket PC)
