To change PC to use the software GEOMECA 4e:

    When you formatted a PC or  bought  a new PC  and  when there is a situation to change a using PC  to another PC because of  moving a seat etc., you can receive certification for the software GEOMECA 4e to be used  at a new PC  or a formatted PC  for the rest use-contract term after the use-contract condition is inherited. But, the previous PC cannot receive certification, so if it is not needed any more,  I hope you eliminate it at the previous PC.

  • You should select  PC (A) to change among  using computers and  PC (B)  to use instead of  (A) among computers not renewed or a new PC.

  • B is exchanged with A or is substituted for  A.

  • If you select a new PC,  please input the unique number. And, in third step, you should click 'confirm' in the web page after confirming 'Fail' in the certification screen by executing the program at the PC to use newly. At this time,  when two sending unique numbers are the same, the substitution is approved .

  • The unique number is confirmed in the information of software GEOMECA 4e's help or through the reported explanation of certification screen when executing the software.

  • For what is using, if you change it and are going to change it one more time, then that is possible after 30 days. Also, if you change it after 30 days and are going to change it again on more time, then the change is possible after 365 days. Therefore you can change it up to maximum 2 times in 1 year.  The time when the change is possible repeats the process which is 30 days later and 365 days later after changing.

  • The PC received permanence certification with file or key cannot be changed by internet.  If you formatted it, please contact me.  In this case, you can receive permanence certification only once one more time with file or key.
