Dear PTC Community,

I have Mathcad-11 from the 1990's, & I need to reinstall it after a HDD failure. However, PTC (Mathsoft) doesn't run their license server anymore & therefore, the product cannot be activated.

Can someone please assist ?

Thanks Vivek, I sincerely appreciate you bringing this to me attention. Unfortunately, it does not fit my problem. I either need the license server to be reactivated, or I need someone at PTC to provide me with an Activation Key. Do you know any direct point of contact within PTC whom I may approach for the information I require ?

Quite frankly, if I can't get assistance, this tells the public not to pay thousands of dollars for a Mathcad License because one day your ability to use it will be taken from you, & a great deal of money will have been stolen from you; from my perspective, deactivating the license server is equivalent to theft.
