Fixing the PDF preview handler in MS Outlook

I was having issues with previewing Adobe PDF and MS Office documents in MS Outlook 2010 i.e. preview didn’t work and the message “This file cannot be previewed because of an error with the following previewer: PDF Preview Handler for Vista” appeared instead. I’m running Windows 7 but it applies there as well, so I looked for an answer and thought I’d share.

This solution was provided by Leo Davidson who has also written a registry fix utility but I elected to do the fix manually.

First, open regedit.exe and browse to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\
CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193}

2013-01-21_130325
Now change the AppID value to the following

{534A1E02-D58F-44f0-B58B-36CBED287C7C}

Click OK and you should be able to preview PDF and other files. It worked for me, so thanks Leo.

“We made the buttons on the screen look so good you’ll want to lick them”

- Steve Jobs, on Mac OS X’s Aqua user interface (Fortune, Jan. 24, 2000)

Between the times when I’m doing something useful with my home PC, I like to tweak settings, replace or add hardware and generally try to optimise things in an endless quest to make it start faster, run better or do tasks more quickly or easily. This inevitably leads to a point where the PC doesn’t work at all. The fun then is restoring it to working condition in an endless cycle of OCD madness.

Apple has gone a long way towards protecting me from my self-imposed tenth circle of suffering by producing devices that prevent such levels of customisation. Their elegant design and inherent usability may take away some of the fun but they have also signalled a new world order in computing.

According to research company NPD DisplaySearch, more tablet computers will be sold than notebook computers in 2016. Microsoft is making an even bolder claim by predicting that tablets will outsell standard PCs during 2013.

Samsung Galaxy Tab 2 10.1Designing for a tablet presents some interesting challenges, not least in the design of the user interface which needs to embrace the standards and paradigms of tablet computing. The most obvious of these is the replacement of mouse navigation with the less precise navigation of touch. The ability to manipulate objects directly by touch provides a more engaging user experience and if virtual objects are metaphors for real objects and actions then tasks become more intuitive.

A Great User Interface

A touch interface also means the need for larger controls and moving away from traditional menu based user options to consider for example, having translucent bars and fading controls that appear and disappear as the user interacts with the application. With limited space for larger controls we also need to think more carefully about what is needed on each screen and whether it is critical to what the user needs at the time. If not, then perhaps it’s critical in a different context, or maybe not at all.

A great user interface is not however centred on the capabilities of the device but on the way that users think and work. It makes the difference between an application that inspires users and one that is tortuous and demotivating to use.

The widespread use of tablets may provide the impetus for us to re-think user interface design in general and perhaps inspire us to move to the next level in human-machine interaction.

They call me mellow yellow*

I try to keep the many and various areas of my work separated by the obvious means of creating lots of Windows folders and sub-folders. For easy access, I’ve prefixed the top five sub-folders with a number so that arranging by name places them at the top in my preferred order. Another or additional method would be to have the ability to change each folder icon to something more meaningful, colourful and ideally attractive so that it stands out from the standard yellow icons. Amongst others that aim to achieve this, I found ‘Folder Marker v3.2′, which is a shell extension utility to customise folder icons. I thought I’d give it a try.

folder marker context menuHaving installed Folder Marker, as you might expect from a shell extension, it met my first acceptance criterion which is the ability to use it from the context menu to change a folder’s appearance on-the-fly. A right click on a folder (or secondary mouse button click) and selecting ‘Mark Folder’ brings up a sub-menu that lists folder colours, favourite folder icons, more icons and the option to restore default. Click one of the listed icons and it’s job done, your folder icon will change accordingly (you may need to do a simple refresh).

A two click process

It gets better though; the icons in the context menu can be customised from the available icon sets which in most cases makes changing a folder icon a simple two-click process. Nice. Compare this with ‘Lovely Folders 4′, an excellent and similar utility, which requires at least six mouse clicks to change a folder icon. Folderico is also similar and appears to offer a context menu option but in fact this only works for 32bit Windows.

Folder Marker will also handle multiple folder changes, just select all of the folders in the normal way and click the required icon to change the whole group.  Selecting ‘Apply selected icon to all subfolders’ does what it says. All very neat.

The menu item ‘More Icons’ opens up the main application to provide a wider selection of icons from tabs named as ‘Everyday, ABC, Main and User Icons’. The latter as it implies provides the ability to add your own icons.  The Action menu includes ‘Customize Mark Folder’ menu item, which gives access to customisation of the icons available in the context menu.

folder marker mainFolder Marker is available in three versions, Pro, Home and Free. The main difference between the first two is that the Pro version targets the office worker and has support for changing network folder icons, it includes additional work related icons and the changes to icons can be made distributable or portable.

Folder Marker Pro is priced at $34.95, Folder Marker Home is $24.95 and both are available for download and trial at http://www.foldermarker.com

An additional 60+ set of (so called Vista) icons can be purchased for $19.95.

The reference to Vista (Windows 7 has been around for nearly 3 years) and the lack of any recent updates is a concern and would seem to indicate that maybe development has stopped on this product, which would be a shame. It’s also quite expensive for a shell utility (when there are freeware alternatives) and I think that the extra icons should be included in the basic price of the Pro and Home versions, otherwise it’s excellent and probably the best of its kind.
