Canon Camera Window Problem

My installation of the Canon camera tools got severly messed up when I installed a new version of the software (Camera Window and ZoomBrowser) on top of an old version. I think the problem arose because I installed both versions from different user accounts. (I have a multi-user Windows XP setup, which some software wasn’t written to cope with.)

Anyway - the symptoms are that after you plug in the camera, Windows recognizes it, but the download window doesn’t show up. For one user, it works, for the other it doesn’t. The weird thing is that I could watch the process list and see the app (CameraWindow.exe) start, but then quit without showing any error message.

After much mucking about, I tracked it down to the permissions on the registry keys. One user had permission to modify the keys, the other didn’t, so the application quietly failed. I couldn’t even re-install the app, as I didn’t have permissions to write to the HKLM\Software\Canon key.

To fix it, I uninstalled as much as I could, switched users to find who had permission to alter the registry key, deleted it, then reinstalled the software. I actually reinstalled (the same version) for all users this time, but probably could have just modified the permissions on the registry keys for all users to have access.

Mapping Bath

Last weekend, a gang of OpenStreetMappers descended upon Bath in the UK. I went along, to lend a hand, armed with my trusty Geko and a bike. I had already made an attempt at mapping the town ccentre, but not much outside the old city walls was done.

My first day’s results can be seen here, the second day’s work here, and all the raw data from the weekend from all the people involved is shown here. For only two day’s surveying, I think the amount of coverage is pretty impressive. That’s only the raw data though. Now lines need to be drawn on top, using vectors, then those vectors combined to make streets and the attibutes, tags, added, such as names, size and restrictions.
