When trying to run the Quickmap Data Setup to install data or Quickmap Expansion packs such as QExpansionSetup.exe, you may get this error:

Quickmap Data Setup …

vector <T> too long

This happens because the file path that the file is saved to by default, is too long.

To fix this, instead of clicking Run from the browser, click Save and save (or copy) it to a folder location with a shorter name. After the file has finished downloading, navigate to the file and run it.
