Installing .Net 3.5 onto Windows 8 and 8.1 using DISM

This is one of those posts to save me searching the web every time I need to install .Net 3.5 on a Windows 8 (and now 8.1) system. If the automated installation via add/remove features fails then you need the correct DISM command.

For those who have not yet encountered it, DISM allows you to perform actions on Windows image files in a process called Offline Servicing. However, it also allows you to perform the same functions online – on your current windows system.

There is a handy TechNet post on the various ways of installing .Net 3.5 on Windows 8. It’s a useful reference.

For those, like me, who just want the quick steps:

  • Grab your Windows 8 media – USB stick, mounted ISO or DVD.
  • Open an Administrator-level command prompt.
  • Type: Dism /online /enable-feature /featurename:NetFx3 /All /LimitAccess /Source:x:\sources\sxs Where x is the drive letter of your source media.
  • Watch the installation progress. Job done.

More UK TechDays on System Center 2012 and Windows 8

Our good friends in the UK TechDays team have announced another raft of events in their fantastic IT Camps series. I’m hoping to be there for at least on of them and if you’re at all interested in Windows 8 or System Center 2012 I cant recommend them highly enough.

No slides, no marketing – just technical content, demo driven with as much audience participation as they can manage. Everyone I’ve spoken to at previous camps has enjoyed them and learned a great deal.

I’ll be helping with the server camp in York on the 5th of March and you might see me at other camps too.

Enough of the gushing plug, here are the dates and venues, with links so you can register:

Speaking at Designing Beautiful Windows Apps in Dublin

I’m really excited to be presenting at a one day event on Windows 8 application design in Dublin on Wednesday 26th September. I’m excited because Bill Buxton is delivering the keynote at the event and I’m a big fan.

I’m delivering a session snappily titled ‘From 8 to 88 inches: designing for everyone’ and I’ll be talking about the challenges posed by the incredible variety of devices Windows 8 will be used with.

If you are attending the event, come up and say hi. It will do me good to chat, because the event is being streamed live! I’ve never presented to the entire planet before, so I’m unusually nervous about it!

It promises to be a great event, and I’m pleased to be involved with our friends from Microsoft Ireland, with whom the Black Marble irregulars have run many events on a wide range of topics over the past few years.
