Office Web Applications Installation Issues–Be VERY Careful

Published September 22, 2010

I’ve recently had a few issues with Office Web Applications (the other OWA). I’m of course referring to the versions that run on SharePoint. In all cases, the typical installation routine is to lay down the SharePoint code (either Server or Foundation), configure the farm with the Products configuration wizard, then install the Web Apps and run through the Wizard again. There are variations on this, and you can use Powershell instead, but in all cases, you need to run through the configuration wizard after you lay down the Office Web Apps code.

The problem arises when you start uninstalling stuff.

In the first case, I was working with an Enterprise farm, and I needed to uninstall the SharePoint bits completely, so I would then remove the server from the farm, uninstall the bits, and then re-join it. So I went ahead and did that,but hit a rather nasty error when I tried to reinstall the SharePoint bits – “The install in progress conflicts with a previous installed MS Office 2010 Server Product.”. It turns out that it was the Office Web Apps Installation that I hadn’t removed first.

No problem,right? I’ll just uninstall the Web apps and all will be good. Unfortunately, no. I went to Control Panel, Selected the Office Web Apps, selected Uninstall and got an error stating that Office Web Apps had already been uninstalled, and would I like to remove it from the list. Not cool. I eventually had to resort to hacking through the registry and removing references to the apps (it was a dev farm so no problem). The second time I did this (yes I know, fool me once shame on you….) I wound up having to re-stage the whole server.

So then logically, you should really make sure that if you’re going to uninstall the SharePoint bits, you need to be very careful that you remove the Office Web Apps beforehand (and run the Product Wizard).

This brings me to my next scenario. I was recently working for a client that had SharePoint Foundation installed, and wanted to search PDFs. It turns out that this isn’t possible with Foundation (it was in WSS with a registry setting), but you now need to install Search Server Express. No problem, it’s free, and it’s a better solution anyway. I downloaded it, and installed it, and guess what error I got? “The install in progress conflicts with a previous installed MS Office 2010 Server Product.”. Well, I’ve seen that one before. It didn’t take me long to figure out that Search Server Express doesn’t like installing on top of Office Web Applications.

This time, all I needed to do was to uninstall Office Web Apps. No problem, I uninstalled it from control panel and all looked good. I then ran the Products Wizard to make sure everything was going to be put back properly, and the first thing that it asked me was whether I wanted to create a new farm, or join an existing farm. Excuse Me?????

So here’s the other big thing to note. If you uninstall Office Web Apps, it will remove the server from the farm. It might have been nice to know that ahead of time. Luckily, it was a complete install, and I had all of the necessary credentials handy including the farm passphrase.

In case you’re wondering, yes, Office Web Apps went back on top of Search Server Express just fine.

So just to recap:

1. Never, ever, uninstall a SharePoint 2010 product is the Office Web Applications are installed

2. You can’t install Search Server Express on a server with Office Web Applications already installed (they can be installed after)

3. Removing the Office Web Applications removes the server from the SharePoint farm.

License State Error Joining a SharePoint 2010 Server to an Existing Farm

Published August 7, 2010

I ran into an interesting error this week at a client site. They had been having server trouble, and that involved setting up a new instance of the operating system, and obviously all of the SharePoint bits needed to be reinstalled. Once that was done, I ran the Products and Technologies configuration wizard, set it to join an existing farm, entered the farm credentials and everything was good until Step 3 – where it connects to the configuration database. At that point it choked with:

“The license state for the current server doesn’t match the farm’s license state.”

My first impulse was that I had used the wrong key when installing the bits. Trying to join an Enterprise farm with a Standard server, or vice versa could cause this, but I was able to confirm that I had used the right key.

After a fair bit of head scratching, I realized that I had committed the mistake that I always commit with 2010, and I had forgotten to install the Office Web Applications. I had indeed installed them on the farm, and the rebuilt server did not yet have it installed. After installing them, I was happy to see that the server joined the farm successfully.

Storing Data In The Cloud

Published June 21, 2010

Last week, my colleague Ed Senez posted a very good article about cloud computing, and it’s benefits.Our company has been making moves toward the cloud for a couple of years now, with both Microsoft’s BPOS offering, and our own SharePoint Extranet Accelerator. While companies struggle with the benefits and risks of moving pieces of their business to the cloud, I can see a huge role for the cloud in the consumer space, primarily because it is so cost effective. I have been moving a lot of my personal data to the cloud for the past little while, and I thought that I would share my current observations.

Photos and Videos

Almost any Facebook user is familiar with posting pictures. The social functionality is great – tagging people lets all their friends know that they are in a new picture (maybe not so great if you don’t like the picture, but I digress….). YouTube is of course great for uploading and sharing videos, but both of these services have one drawback – they convert the files on upload resulting in a loss of fidelity. If you care about the quality of your source content, you can’t rely on these services for backup.

This fact led me a few months back to Flickr. At first look, Flickr had a lot of limitations too – a maximum file size,and a maximum upload rate per month,which initially caused me to dismiss it. What I found out was that with the subscriber version there are no limits at all – you can upload to your hearts content, and it will store the images in their true source format. I have been doing just that when I could for the past few weeks, and currently have over 2000 pictures in my photostream. Just 8000 or so to go.

Flickr also allows you to share your pictures publicly, with family and friends, or just keep them private. However, Flickr doesn’t have Facebook’s ubiquity, so I use it for purely public pictures only, and continue to rely on Facebook primarily for sharing and people tagging. Flickr does allow for videos as well, but it does have some size limits, so I will be relying on YouTube for sharing my videos, along with a separate backup strategy (see below) as I get my videos organized.

So how much does this cost? For $25 per year, I know that all of my personal pictures are backed up. Pictures are quite literally irreplaceable. Documents can be recreated, but you’ll never have a chance to capture those precise moments again. The fact that I can use the services to share picture (in full source quality) is really just a bonus.

Simple Storage with SkyDrive

Did you know that you have 25 GB of storage in the cloud that you can use free of charge? If you have a Windows Live ID (also free..) then you do. It’s called Sky Drive, and it’s extremely handy. Simply upload the files you wish to private, shared, or public folders and they’re safely secured away and accessible from any machine with a web browser. Because SkyDrive also uses WebDAV, you can map your SkyDrive folders directly to folders on your computer.

When you are navigating through your SkyDrive, you also have access to the recently released Office Web Applications. These are light, browser only versions of Microsoft Word, Excel, PowerPoint, and One Note, and they’re completely free of charge. You can create a new document using these apps, or edit anything that you upload. These apps are very handy for occasional use, for viewing purposes, or just for accessing an Office document that may have been sent to you when you don’t have the Office applications readily available.

Sky drive should pretty much eliminate the need for FTP servers, certainly for personal use. Given the cost of the service ($0.00), I really don’t see why someone wouldn’t want to take advantage of it.

Backup

I think that everyone that has used a computer for any amount of time has at some point lost data. Afterwards, there is a mad rush to back up the systems, and then make sure that there is a system in place to back everything up. Corporations typically have solid backup strategies in place (that aren’t tested frequently enough, in my opinion), but personal users are often too busy to ensure that their data is backed up in a timely fashion. There are a ton of consumer backup product out there, but they all often have one fatal flaw. They require the user to actually do something to make it work.

This is where the cloud can be of great help. If we can assume that the machine will typically have a connection to the internet, then for all intents and purposes, our backup destination is always available. All that is needed is a good service to make this painless and automatic for the end user. There are a number of such providers out there, and I’m going to briefly discuss the one that I’ve settled on – Carbonite.

With Carbonite, you download a small application that runs in the background, and is constantly ensuring that your files are being backed up. For most users it is as simple as a next – next install, which will backup all standard data folders. If you want to back up a non standard folder, just right click on it and choose to add it to the backup. You can always see what the backup status is from the console, but carbonite also (optionally) places a small indicator over the icon for each file that you have to let you know its backup status. The backed up files are also browser accessible from any internet connected PC, allowing you to access your files in a pinch, and one of the nicest features is that it not only keeps a mirror image of your system off site, it maintains file versioning, so when you make a change to a file and later decide that it wasn’t such a good idea, you can retrieve a previous version.

Given most end users’ bandwidth constraints, the initial backup can take a little while. Mine took two weeks, but that’s me. After initial backup, it all goes very rapidly. So what’s the cost of all of this storage? You can back up as much as you want from a single machine for $55 US per year. To me, that’s a no-brainer.

I spend about 5-10% of my time inside my company firewall. Tools to help with remote connectivity are crucial, and I really see a place for cloud based services to provide a lot of these tools. They’re safe, they’re easy, they’re useful, and they’re highly cost effective. In storage alone, I now back up all of my important personal data (redundantly I might add) and enhance my convenience in accessing it. All for less than $100/year.

I’m sold.
