Postureminder is working fine but my other applications lose focus while I'm working

Postureminder should not take focus from other applications so if this is happening whilst Postureminder is running, and stops happening when you exit Postureminder, it may be a problem with your webcam.

Please try uninstalling any free software that came with your webcam, so that only the webcam drivers remain. Also, please make sure your drivers are updated to the latest versions - open Device Manager by right-clicking on My Computer, selecting Properties, then clicking on the Hardware tab and clicking the Device Manager button. Go down the list to Imaging Devices, click to expand it, then right click on your webcam and select Update Driver.

If these measures do not solve the problem, please let us know via


Postureminder can't access my webcam even though it seems to be working in other software

If your webcam works fine in other software, but you find that Postureminder can't connect to it (e.g. in the Calibration screen) there may be a number of causes.

First, check that your webcam is not in use by any other software. You may need to restart Postureminder after closing the other programs so that it can try to connect afresh.

It's also possible that the free software that came with your webcam, or other applications such as Camtasia Studio, are interfering by putting unusual filters in between the webcam feed and Postureminder. Try uninstalling your webcam, then reinstalling it but opting only to install the webcam drivers (you may need to refer to your webcam manufacturer's documentation for advice on how to do this).

Another thing to check, especially if the calibration screen shows a blank rectangle where the webcam image should be, is if there is a file called "cameramethod.pml" in C:\Program Files\PostureMinder.  If not, it may be that Postureminder has tried to create this file but not been able to because of folder permissions.  Try right clicking on the PostureMinder folder, select Properties and go to the Security tab.  Select  Users from the Group or user names box, click Edit, and make sure Modify and Write are allowed.

If these measures do not solve the problem, please let us know via


Postureminder can't find stretch exercises even though files are present

Webcam connection issue: Postureminder encountered a problem trying to use Method: "Special1" to connect to webcam...

If Postureminder reports this error when trying to connect to your webcam, it may be that the software installed with your webcam is interfering with your webcam.

Many manufacturers install, as default, various software toys such as face tracking or special effects which can get in the way of Postureminder accessing the webcam. To avoid this, please uninstall the software that came with your webcam, then re-install but opt only to install the webcam drivers.

If you continue to encounter problems, please contact with full details of your webcam and the problem you are encountering

Webcam flickers/incorrect posture reminders

There may be a number of causes for receiving incorrect posture reminders, usually related to adverse lighting conditions. One issue to check is the camera settings - most modern webcams have an Anti-Flicker setting. If, when viewing the webcam output in the calibration window, or in other software, you notice flickering behaviour, please check that this setting correctly reflects your location.

Contact if you require any help with this

Dell computers + Logitech webcam leads to Windows crashing or applications stopping working

There is a reported problem with the hardware inside some Dell computers being incompatible with older versions of Logitech Quickcam drivers. This problem appears to be related to older versions of drivers for the built-in microphone.

To fix, right click on My Computer, select Properties->Hardware->Device Manager. Under Imaging devices right click on your webcam and select "Update driver..." Under Sound, video and game controllers locate the Logitech Microphone (Quickcam) and again update the driver.

If this doesn't correct the problem, try going back into Device Manager and choose to disable the microphone


Installation problem: Error 1723

If you encounter a pop-up error during installation saying something along the lines of: "Windows Installer Error 1723: There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor," this is because your computer does not have an up-to-date copy of the Windows Installer package.

Please search online for a file called WindowsInstaller-KB893803-v2-x86.exe - it should be available from the Microsoft website. Please run this to update your version of Windows Installer, then try installing Postureminder again. This is only an issue with older versions of Postureminder.

What our users say...


Helen Killeen, Business Manager, Glaitness School, Orkney:
"I am impressed both as an employee and a manager with Postureminder. It helped me personally to adopt and sustain good habits when keyboarding. As a manager, the fact that employees receive integrated ergonomic training and self-assessment report as part of the software package means it is great value too!"

David Brewerton, Programmer and posture blogger at
"There are other software packages available but PostureMinder is the best Iíve seen and after two weeks Iím convinced that it is actually improving my posture and easing my pain problems"

Aaron Gammon, Professional Musician:
"Postureminder continues to help me improve my sitting position both during my day-to-day computer use, and during my regular practise as a percussionist. Used intelligently, in my case in conjunction with other techniques, Postureminder has proven itself to be an invaluable tool in my ongoing efforts to improve my posture, health, and well-being. Initial use of the software was quite an eye-opener for me! Although I felt that I was very aware of my own back problems, I was extremely surprised to what degree the posture I unconsciously felt was 'correct' actually was out of alignment. I am grateful that this intelligent software exists, has been developed and is maintained, and cannot recommend it highly enough. "

Andy Woods, PhD (Trinity College Dublin):
"Postureminder's gentle reminders to sit up straight are great - I am a psychologist and recognize that consistent unobtrusive feedback is essential in making any such change in your life. Thank you PostureMinder for improving my posture :-)"

Margaret Chou, Marketing Administrator, Lamri Ltd:
"I bought Postureminder 18 months ago and it's made a significant improvement to my working style. I spend a large proportion of the day at my desk but with Postureminder I donít end up hunched over my mouse exacerbating my shoulder problem. This is the next best thing to having my chiropractor sitting next to me and a whole lot cheaper"

Aaron Gerstonkorn, Muniworks, US:
"Really love your product, it has really kept me in the right position and helped reduce eye strain with the micro breaks"

Tim, Business Recovery Partner, leading UK accountancy firm:
"Better habits are ensuing...It's certainly helped me"

Sue, Vocational Rehabilitation Consultant:
"It proved very useful in identifying when I was not sitting correctly. It helped me to improve my posture a lot. Iíd definitely recommend it to computer users, especially those with existing musculoskeletal disorders"

Liz, Software Tester, Manchester:
"I'd been having back problems for three or four years and even had to take time off work when it got too bad. I've also had physio to try to help alleviate the pain. Since I started using Postureminder my back pain has definitely improved"

Diane Kermode, MD of Beechwood Occupational Health Ltd:
"Postureminder is a good, uncomplicated product which acts as a safeguard for businesses to use to protect and educate employees. It will be very useful for those with pre-existing postural or musculoskeletal problems"

David Nesbitt, Private Chartered Physiotherapist, Whetstone, North London:
"As a physio I have found Postureminder really complemented the advice I have been giving my patients regarding posture and their working environment. A great concept, very user friendly and an essential tool for all computer-based workers"

PC Advisor magazine review:
"Postureminder is ideal for those concerned about how they sit now, or want to prevent problems in later life. The sooner you can start sitting right the better."

Michael van Straten, Health Journalist of the Year:
"Backache is one of the most common reasons for lost days at work and it's also a frequent problem for young children. Latest research shows that long periods at a computer can cause backache, pain in the neck, headaches and RSI...Around 32% of us sits for 10 or more hours each day, slouching in front of PCs and TVs. This bad posture is the trigger for back pain. [This] award-winning system will change how we all sit at computers. PostureMinder is new software that watches while you work. It sends webcam messages if you slouch, shows how to set up workstations and tells when you need a break"

Leading Physiotherapist Christopher M. Norris MSc MCSP MBAcC:
"Norris Associates have been providing occupational health services to bluechip industries in the Northwest for over 20 years now. During that time we have worked with clients such as Jaguar, Shell, Kelloggs. One of the factors which is the source of many painful conditions in office workers is prolonged sitting at a computer. This constant low level stress causes muscle fatigue, neck and shoulder pain, and back conditions. To combat this type of occupational stress our physiotherapists often recommend taking regular breaks and performing simple stretching exercises to prevent accumulated stress in the body tissues. Well, now we have found an excellent software program which encourages users to do just these things"
