I tried Demo version. The softwares developed by you are very useful & handy.

Great program! Easy to use, you get the results really quick. A real lifesaver if you need quick, accurate calculations.

Hi Yah, I downloaded the Avira uninstaller yesterday for removing the antiviruis, but it was unable to remove the application. Finally, I downloaded the original antiviruis from the Avira website and get it removed by running the application.Stay happy

Yes I would like to post a comment on the Avira Antivir product, it\'s been over a year since I \'uninstalled\' your product, but every time I try to upgrade my Operating System even after using the removal tool and rebooting the system Windows 7 still refuses to install due to Avira Antivir leftovers, get your house in order please, I want to be free of your product. Disappointed Glenn Dalgarno

This tool worked great, I tried installing Avira about three or four times and kept getting a message that a previous version was still installed.After running this tool and it cleaned up the registry it installed without a problem..I will definitely use it again even if I have to pay for it.

I tried to download the Avira removal tool, with NO success. Did not happen.Avira was recently recommended by Consumers much to my dismay. It is an invasive infective.I would like to say malware; but do not want to be sued.I am still living with the insidious problem.

I download Avira from my laptop to a jump drive and then to a desktop infected with System Tool 2011 v 2.20. However, the infected desktop will not permit the down load telling me that Avira is infected and cannot be activated.Any suggestions?Bob

I was trying to find a product to totally remove Avira Antivir Personal Edition which is impossible to remove from my computer. I have done everything including re-install it and try to totally remove it again - nothing has worked - I have gone into the Registry and removed all traces, etc. - it remains !!! The removal tool is advertised as being able to remove it totally - I was unable to download it for two days - then I got your email and downloaded it from the site you provided - I ran it and all it did was ...

I recently downloaded what was presented as a part of security essentials but turned out to be a rather nasty virus.Tried SMS uninstall, made it worse. System restore helped but barely. Managed to get Avira and ran it. Great job. Worked beautifully. Three days later and still have some minor issues,but working OK.Solid product,I highly recomend!

Advertised as a free Tool. Once downloaded and scanned computer and found problems - you are then told you have to pay so much to buy program to fix problem. It was not free at all. I went and bought a known program as at least they advertised it would cost something and I trust them more than someone who advertises something that is free when it is not. Cheers Glenn

Opinion. Good software, really helped me a lot.

Is'nt what i wanted...does not clear the virus propely...did'nt like dis...

Opinion. It's very nice it helped me out. But it is some what slow take some time but very nice soft ware.

I have tried Avira AntiVir Removal Tool and a couple of other products and all of them have had varying degrees of detection; i.e. some will detect things that others dont.Overall all three products do delete what they detect but they have not been completely successful in permanently removing all the malware from my system. They just keep coming back.

nice workveerachari,Design engineer

the program is not working !!!!!

even a bricklayer can.... I hope to enter my 90' Lincoln Mark Vii in the 100 mpg race next year. I needed a way to redesign my AOD transmission for racing and I couldn't get my modeling software to derive the design. MITCalc was easy to figure out, even for this bricklayer. I hope to have the fastest car and contribute to helping America climb out of this economic delima. Check out my progress at w.w.w dot evloansfor dot us

Updation We already bought the MITcalc software an year ago. In that there is no planet gear option. The newly developed is very useful for us. Can we get free update for Mitcalc.

A useful tool, I used it to check an existing calculation. However it takes a while to understand how to use it. Overall I'd say its good and I'll use again.

I am looking for Rack & pinion gear calculation.how i can use this sheet to get required information.

The program works very well. I will evaluate it a little further before deciding whether to purchase as it appears far in excess of what I need

Dear Sir/Madam,Before buying your software I checked the demo. of your module for spur and helical gears calculations.Unfortunately the only option I found is calculations without errors, means I could not check tolerances/deviations of dimensions over pins subiect to backlash limits or even change backlash in the table and receive result to this data (all data are for \"0\" backlash without any possibility for changes), posibility to modify tooth thickness and get the dimension over oins or span over teeth, entering DIN or ISO or AGMA quality grade and receive tooth errors/deviations etc.In case there ...

We are looking for program to check existing set of gears, unfortunately Spur Gear Calculations 1.16 do not support this type of calculations.Regards,Steve

MITcalc review Your spreadsheets for Metric-ISO gear design are very good. But we badly need a good comprehensive textbook in English. It seems that the only good books are in German. I bought 4 of your gear design spreadsheets.Thanks for your good work.Prof. Hatem Radwan

MITCalc Review It is a quite easy-to-use spreadsheet. The main advantage is that it is like an algorithm; if you follow it step by step, you will end up to a result. Its disadvantage is that it doesn't comply with other standards, like DIN and ISO, and it could be as an option. Nevertheless, it is quite good for solving simple pair of gears, and the results are more than satisfactory. I use it mainly to have a preliminary calculation before I turn to the original AGMA analytical calculations (that is, all the background calculations that the spreadsheet does) or to check ...

Dear Sir/Madam,My name is Ehsan and I am doing my PhD in electrical engineering. In the direction of my thesis I have to compare the dynamic model of bevel gear with Spur one. I was wondering can you help me in this regard and provide me some information or reference for me.I would appreciate if you could reply back to me.Yours faithfully,Ehsan
