Windows Vista - ClickOnce and MSI
Windows Vista - ClickOnce
When ever you install software on Vista, investigate the capabilities of ClickOnce. Incidentally, 'Click Once' also provides a intriguing case study of how systems evolve and integrate.
Firstly a
confession: I originally thought that ClickOnce was a successor to the MSI installer - wrong. ClickOnce is a web based alternative to MSI. ClickOnce evolved from the 'no touch' concept developed in
Visual Studio. Perhaps the phrase, web based application helps to classify ClickOnce. I am sure when (if) you next install internet packages, those Authenticode certificate messages ring a bell.
ClickOnce can deliver such applications for your network users.
MSI Installer Packages
What's new is integration between MSI and User Account Protection. The result is that you don't have to logon as
administrator to install MSI packages. If you need administrator's rights, then Vista displays a dialog box to enter your password and so temporarily elevate your rights. A new trend is for the default behaviour to only
install the package for the current user, not All Users. You can still give everyone access, but as an option not as the default. I imagine that these strategies are for peer-to-peer
networks, because if I were in charge I would deploy all software via Group Policies.
.
Integration Summary
ClickOnce applications are created or published by Visual Studio 2005.
Authenticode certificates give users extra confidence.
BITS can perform trickle installations of large applications in the background.
User Account Protection allows you to install as an ordinary user, and just supply administrator credentials as needed.
Restart Manager reduces the need for a reboot. Instead it just restarts the relevant services.
Vista Developers
ClickOnce and MSI are a developers heaven. No new software can be installed without Visual Studio 2005 or Windows Installer (MSI) technology.
Train Signal has just released their
New Windows Vista Training Course. As an MCT
trainer, I am a huge advocate of Train Signal’s products. What impresses is me is that they demonstrate everything that they teach and they stay away from traditional 'lecture-style' training. If
you are looking for a complete DETAILED coverage of Windows Vista, then I highly recommend that you give this course a try. I have reviewed their 18 hours of videos myself, and I guarantee that you will
not be disappointed!
This ebook will explain the workings of the registry. I thoroughly enjoy tweaking the registry, and I want to distill the best of my experiences and pass them on to you.
Each registry tweak has two aims; to solve a specific problem, and to provide general learning points, which help you to master regedit.
