Renewal confirmation matter

    The latest order number and registered password are needed. In the special CM, if you are going to add certifications for some serial number, then the serial number is needed.

    The unique number is shown in the information of the software's help.

    You should select 'yes' or 'no' of using the software continually at the PC related with the unique number. 

  • If (Renewal number of certifications)  is grater than (the number of what selecting 'yes'),   then  the software is allowed to install to another PC as many as the number relating with the difference and will be received certifications.

  • Only when (Renewal number of certifications)  is grater than or equal to (the number of what selecting 'Yes'), the order is transmitted.

  • The PC of the unique number selecting 'no'  can be used only up to expiration date.

  • Later, when you renew the order again, if you select 'yes' for the stopped unique number, the software can be used again at the PC.

  • You can renew '1 year' to permanence. After ordering with permanence, only permanence certification addition can be ordered for the related serial number.


 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 that 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.
