Don’t know what the catch with this one is but I was caught a couple of years ago when purchasing Autocad LT2016. It was advertised for around £250, cannot remember exactly how much now, it’s an age thing, anyhow the CD arrived and a link to a website telling you how to install it. To cut a long story short everything was ok until I had to request a serial number, there was some key code generator and every attempt was not recognised. After a couple of weeks of complaining to the seller he grudgingly refunded my money, I ended up buying Alibre Atom instead and have been more than satisfied with it.
I did the same and also had the same problem. Autodesk are very good at protecting their software!! They also stop supplying replacement serial numbers when you re-install Autocad on a new computer, after a certain number of years. I have a genuine copy of Autocad that I bought from them, but when I wanted to transfer it to my new computer,k a couple of years ago, they refused to provide me with a new serial number, saying that my version was outside the final date for re-issue, by 2 weeks!! When I was a draughtsman, I bought my own Autocad and bought every issue from Release 11 up to Autocad 2004. That was roughly, a new set of software every 2 or 3 years. That cost me probably a total of £20k to £25k over the years, but Autodesk wouldn't take that into account, so I lost the use of my full system that had 3D on it. I have tried a couple of Autocad buys off Ebay, but as Millman has found,the additional software to generate a serial number just does not work!!
It won't work for exactly the same reason as I quoted above. When Autocad is activated it is a 'One Time' activation. When it is re-installed on another computer, it will need a new serial number from Autodesk, and their software is no longer a lifetime software, in UK. It is rented. You pay a fee every month, 6 months or 12 months, and it has to have a replacement serial number to keep it going. That is what I understood from the blurb they sent me when I wanted to get my Autocad 2004 re-installed. Superb software (was), crap company (is) !!!!
Lost interest in autocad when due to a windows update (not asked for) I lost the complete program. To say that autocad customer service was useless is an understatement. I now use solidworks which I am able to use for £20 a year.
I couldn't agree more!! I have been using Autocad since Release 10, in 1991, and have upgraded every release, except 2002, which was approx every 2 years, when I was a contract design draughtsman, up to the last release Acad2004. Then I stopped upgrading. I wanted to transfer my 2004 release onto a new computer, back in 2018, and Autodesk stopped issuing set-up numbers just 7 days previously. They wouldn't make an exception even though I had spent all that money with them. They wanted me to take out a massively expensive subscription for using it for my hobby. NO chance!! I stuck with my AcadLT 2013 and didn't worry about no longer being able to do 3D drawings. Someone recommended BricsCAD as an alternative, but I decided to save my money for buying workshop kit, and stick with my AcadLT. Autodesk have definitely gone down the proverbiable....in a big way!!!
