It doesn't come with the software needed to run it.

Besides being cheaply made, the device doesn't come with the software needed to used it.  Yes, you can get the software free from a 3rd party vendor but its so confusing its not worth it.  Don't buy this unless you want a lot of hassle.

I could not use it since it requires a Windows version which is not produced and can't operate in compatibility mode.

When I went to install this camera the instructions directed me to a website in Somalia to download software. Um, I don't think so! I am returning this item.

I bought this product recently unsure of if it needed software or not because on one of the quetions and awnsers someone said it didn't need software.  As you can imagine I was bummed out when it did need software. I can imagine it's a great product but it is not worth  it if u do not already have software because software is very expensive.

The problem with this book is that, my copy came with a limited license software to use that, was insufficient for the purpose. Additionally, when attempting to transfer the software to an upgraded computer, the difficulties encountered made it more appealing to look for a different information source. The initial draw is to get the purchaser to buy more expensive versions of the software, a marketing tactic that has grown old and, distasteful.

Its a bit complicated to operate. First you have to buy a small chip since it doesn't come with it, then you have to download the data onto your computer, then....I think you get the point !

The card was as new in the package received, but there wasn't any software disc and manuals included in order to install the device to my computer. So I had to look for the software, which was still available, in the Compaq's webpage.

No instructions on how to use the software after installed.

This was sent without an install CD. Though with the paper included it clearly tells you how to install the software from the CD. tracking down the computer software seems incredibly difficult.  I can find wiring diagrams and software for what appears to be other model's but not this one, very dissatisfied

This software was only $30 but it doesn't do the bones and other features that are advertised for the full software package.  Good tutorials, but it really leaves out too many basic features.

Needed additional software that costs $60. Company rep just keeps sending e-mails on what I needed to do,what kind of operating system I was running and if I had hooked it up properly. They asked what color box it came in and maybe "their" supplier sent the wrong one. After the e-mails about their vendor, they stopped communicating and have not heard from them since or no offer of return of item.(Had the same issues with windows 7 and 8.1/would not play Blu Ray without additional software)

It comes with software on a CD, and even after installing the software it doesn't work.  It seems to be intended for a much earlier version of Skype, and I couldn't find updated software online to let it work with current Skype version.  This is basically useless; don't buy.

From a hardware perspective it's fine. Disappointed with the software that came with it. Specifically no Microsoft office( have to buy) and only 30 days of  virus protection then I have the option to purchase a plan. Wish I did more research and just paid more with software I expected to be there.

I'm giving this webcam a three star rating.  I took two stars off because there was no software included in the box and the installation problems I had when I downloaded and installed it. The software refused to install with a cryptic error message.  So I looked up Logitech's support number and called them.  The first tech dropped the line on me so I had to call back again.  The second tech was helpful and we went through lots of gymnastics which did not work.  He then sent me a different software installer to my e-mail  that didn't work.  We then booted the computer in "Safe Mode" - no dice.  He then blamed it on my computer.  They dropped the call again so I called their support again.  This time another tech sent me different software which didn't work either.  He then just wanted to get me off the phone so he told me that if this didn't work I should e-maill him back and he would get me in touch with level 2 support.  I e-mailed him back and told him his software wasn't even compatible with my Operating System.  They never replied.  I then went searching for my particular error on the Web and found the error under a Microsoft forum.  It wasn't related to this specific software but it described the exact symptoms I was having and their solution worked.  One of the Microsoft system folders on my computer was corrupted somehow.  I simply deleted it and the software then installed.  The Logitech software guys were telling me I needed to reinstall my Operating System.  Well, that probably would have solved the problem but I didn't have a week to reinstall and configure everything again.

I don't blame the support people for not knowing about this particular problem but I do take issue with them just dumping me off and never responding to me again.  It was like they get paid on how many calls they take but not on how many customers they satisfy.

I have bought a lot of Logitech products in the past but I think next time I'm going to try another brand.

Now that the software is installed, the camera works just fine.  I'm using it primarily for Skype calls with my son.  I like the way the camera mounts and it is much smaller than it looks in the picture.  If you are thinking about using it for High Definition Videos, look elsewhere - but for Skype type video calls it strikes a nice balance between price and function.  If the service would have been better it would have recieved 4 stars.

More than likely you won't run into the same software issue I did but if you do, don't expect Logitech support to be much help.

It was okay but had to return it b/c it required you to load software and I purchased it for my work computer for I which I don't have admin permissions to add software.  Not sure if works b/c I didn't get that far.
