<div dir="ltr">Hello Peter and All, Following your suggestion I used 'Synaptic Package Manager' and I installed 'kubuntu-kde-desktop'... It installed 107 files & took approx 10-11 minutes (using my Bigpond ADSL Broadband connection). To cut a long story short... the apps which gave the error msg are now working fine and don't give errors (the one I reported, that is). Thanks for the advice and quick help !!!  ;-))) Fond Regards,          PEW <div class="gmail_quote">2008/7/23 noiesmo <<a href="mailto:noiesmo@gmail.com">noiesmo@gmail.com</a>>: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> peter khelpcenter has dependencies and I think they are not being met automatically when you install on the command line you can do apt-cache show khelpcenter and you will get info on the package and dependencies etc. you may have to install kde desktop to be able to use it noiesmo<div><div></div><div class="Wj3C7c"> Peter Williams wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi Fellow Ubuntu ppl, *SMILE* I have noticed that 2 different applications which use the "KDE Help Center" when I attempt to open the "Help Handbook" (e.g. open the Help / Handbook pull-down menu) I get a error message in a window with an OK button {which closes the message window} I have used the Synaptic Package Manager and re-installed the KDE Help Center -- but the error still occurs. Error message window: Could not launch the KDE Help Center: Could not find service 'khelpcenter' [OK] {button} What is the best way for me to go about getting the KDE Help Center to work again. Note that in the past it HAS worked, but something has broken it :-((( -- Fond Regards, Peter Eric (aka 'pew') WILLIAMS from Hobart, Tasmania, Australia My free website is: <a href="http://pewtas.googlepages.com" target="_blank">http://pewtas.googlepages.com</a> (or) <a href="http://tinyurl.com/yuyejs" target="_blank">http://tinyurl.com/yuyejs</a> (please visit my free website and let me know what you think about it.) </blockquote> </div></div></blockquote></div> -- Fond Regards, Peter Eric (aka 'pew') WILLIAMS My free website is: <a href="http://pewtas.googlepages.com">http://pewtas.googlepages.com</a> (or) <a href="http://tinyurl.com/yuyejs">http://tinyurl.com/yuyejs</a> (please visit my free website and let me know what you think about it.) </div>
