Does http://forums.nbn.org.uk/viewtopic.php?pid=9129#p9129 help? Please note the post that follows it as well. Permissions may also be a problem – see ‘Installing OS map tiles’ at http://jncc.defra.gov.uk/default.aspx?page=4981 . If you have installed with Windows 7 and put the Recorder 6 folder in Program Files you probably won’t have the permissions you need to write to the Map Files folder.

If the map tiles you want to use have been installed in a previous installation of Recorder 6 or Recorder 2002 you can install them using the .gsf files from that, bypassing the map tile selector. Copy the .gsf files to a folder accessible to the current installation but outside the Recorder 6 folder then either install them one by one using Map – Add Background Layer or use the Bulk Load add-in. The ReadMe.txt file that is in the download available from http://jncc.defra.gov.uk/page-4597 explains how to install and use it.

This problem has been ongoing for years. There are many postings on this topic at http://forums.nbn.org.uk/viewtopic.php?id=14
The OS map tiles simply won't install on a fresh install of Recorder 6.
It's high time this problem was fixed, the product is still being advertised and is clearly still not fit for purpose as many other users are discovering.

I downloaded Rec6_OSMapsR6Setup.zip, the software provided by the NBN for loading the OS map tiles into Recorder 6, and retested it on a new laptop running Windows 7, SQL Server 2008 Express and Recorder 6 v6.15.4.238 0000000Q (in C:\Recorder 6 not C:\Program Files\Recorder 6). It can be downloaded from http://jncc.defra.gov.uk/page-4648 . It installed as expected. I was able to place orders as expected and it installed 81 map tiles for me. All the map tiles are listed in the Map Layers box on the left hand side of the map window but they were not visible on the map until I had zoomed in because the Cut In was set to 1:250,000. The Cut Out was set to 1:10,000. If you want to see the map tiles without having to zoom in so far you can change the Cut In to say, 1:100,000,000, by selecting a map tile in the Map Layers box, right clicking it, selecting Properties and selecting a different Cut In. This has to be done for each map tile individually although if the map tiles can be loaded using the Bulk Load add-in you can specify the cut-in and cut-out scales to be applied to all the selected map tiles to be loaded in one operation

If the map tiles software doesn’t work for you there is probably a problem with your installation of Recorder 6 but diagnosing problems like this remotely can be difficult. The permissions need to be checked, e.g. can you write to the Map Files folder? This can be tested by saving any file to it. The Access database needs to be checked. Can you open nbndata.mdb and view the contents of the Setting, Base_Map, Computer_Map and Map_Sheet tables? You will only be able to open this file if you have Microsoft Access installed. If anyone can provide further information that may lead to identifying why this problem occurs in some installations it would be appreciated.
