Calculations PIN number

Step 1. Before paying for on-line calculations, please test to determine if our calculations will run on your computer.

You must have cookies enabled in your browser to perform the test and to use the calculations after you have paid for them.

Enter the password "test" below (lowercase without the quotes) then return to this page (Registration page). If the words "Not registered user" change to "All features enabled" and the "Click to Calculate" button works and adds the two numbers, then the calculations will fully run on your computer after entering a purchased PIN number.

Enter value for A:  
Enter value for B:  
Compute A+B:

Step 2. After testing, be sure to delete the test cookie from your computer by clicking the "Delete Cookie" button below.

If you don't, our home page will say "Welcome Registered User" (since it says that for any cookie set by our server), but none of the calculations will work except the test calculation. You won't be able to enter a purchased PIN until the test cookie is deleted. The test cookie will automatically be deleted after a day.


Step 3. Purchase PIN number for on-line calculations

To activate the Calculate buttons on the entire LMNO Engineering website (all calculations), you may register by securely paying using PayPal by clicking on the credit card image. After paying, a PIN number will be sent to your email address (usually within 1 minute). Then type the PIN into our home page.

We provide the following subscriptions for on-line calculations:

7 days for 1 to 5 computers. $40 (US Dollars).

90 days for 1 to 5 computers. $90 (US Dollars).

1 year for 1 to 5 computers. $200 (US Dollars).

30 days for up to 30 computers. $120 (US Dollars).

To purchase, select the subscription that you would like from the drop-down menu. You do not need to type any comments in the text field unless you would like to. Then, click on the credit card image:

We also accept credit card orders over the phone. Call (740) 592-1890 or email (LMNO@LMNOeng.com) for additional website time limits and computer licenses, such as for a class or large company.

We want happy customers! If you are not completely satisfied with the quality and accessibility of our website, let us know within 30 days of your purchase and we will refund your payment. More information about our subscription service can be found below in the How our on-line calculations system works section.

 

Software purchasing (stand-alone calculations)      To top of page
Any of the calculations on our website can be purchased and run as a "stand-alone" calculation on a computer that is not connected to the Internet. The program will run in the Windows environment.

Before purchasing a stand-alone calculation, please download the stand-alone version of our Addition test calculation, which is the same as the on-line version shown above. To download the test, click on the .exe file below and run it, or save it to your hard disk and run it from the location where you saved it. It is about 40 MB in size, so it might take a while to download depending on your Internet speed. Also, your computer anti-virus and security may warn you that .exe files can be harmful, but ours is not. If the stand-alone Addition test calculation properly adds the two input numbers, our stand-alone programs will work on your computer.

Please contact us before your purchase so that we can tell you how long it will take to prepare the program that you would like as a stand-alone. This is usually a few hours but could be two days.

The PIN-protected programs (the ones with the red plus + on our home page) are $150 (US Dollars) each, and the non PIN-protected programs (the ones with the red dot on our home page) are $50 (US Dollars) each. To purchase a single $150 stand-alone calculation, describe the stand-alone calculation that you would like in the text field. Then click on the credit card image. To purchase $50 calculations or multiple stand-alone calculations, please use the text field and button in the "Consulting and other payments" section. As soon as we receive payment, we will prepare the program(s) and send you an email message with instructions for downloading the file(s). Please read the Conditions of Use.

How our on-line calculations system works
Once you receive a calculations PIN, go to the LMNO Engineering home page, http://www.LMNOeng.com, and type it in. A program will automatically check if your PIN is valid. If the PIN is valid, then a cookie will be saved to your computer. The cookie indicates how many computers can use your PIN and the duration purchased. You will not have to re-type the PIN on future visits to our website unless you use a different computer. If you routinely use different brands of web browsers (e.g. Internet Explorer, Firefox, Chrome, Safari, etc) on the same computer, each browser is recognized as a different computer; so try to avoid using different browsers from the same computer unless you have excess licenses. Your access time (duration) is determined based on the first date and time you type the PIN into our home page. Date and time are determined by our server. For example, if you paid for 7 days of access and type in the password on May 2, 2015, at 8:00 AM, then your PIN expires May 9, 2015, at 8:00 AM. It doesn't matter how many times you visit the website during those 7 days. If you type in the same PIN on a second computer on May 4, 2015, at 11:00 AM, the expiration for the second computer will also be May 9, 2015, at 8:00 AM. If you go back and forth between web pages, you may need to hit the Refresh button for "All features enabled" to appear in some browsers.

Cookies
What is a cookie? A cookie is a line of information that is saved to a special file on your hard disk created by your web browser (Internet Explorer, Firefox, Chrome, Safari, etc.). Most browsers are set to accept cookies automatically. However, if you are averse to accepting cookies, you can set your browser to accept cookies (click the advanced button after selecting options or preferences) when you enter your PIN; then you can turn off cookies. Some people are averse to cookies because they don't want anything written by a website to their hard disk. Cookies do not spread computer viruses, and most websites utilize cookies. If you delete your cookie file, you will be asked to re-enter the password and our database will count that as another of your computer licenses.
