When running V8_ExpansionSetup.exe (AKA QExpansionSetup.exe), you may get this error:

Quickmap Air Photos Install Failed

The following required files cannot be found in the installation folder:
Program/ecw_compressor_2.6_rc1_20020926.exe
Make sure you run QExpansionSetup.exe from the installation folder.

This is typically because you have run V8_ExpansionSetup to upgrade your version 7 aerial photos to be usable in Quickmap version 8, but:

• The version 7 aerials aren’t properly installed, files are missing, corrupted or are otherwise unreadable from this directory (such as due to permissions or a network issue)
• You have not copied the V8_ExpansionSetup to the correct location before running it. It should be run from within the directory specified as the “Image Folder” in the Quickmap Help -> About menu item, and not from within a sub folder of that location
