ELPLA is designed to run on Windows XP. If ELPLA has problems with Windows 7 or Windows 8, follow these steps:


Go to the folder that contains the program package
C\Program Files\GEOTEC Office (32-bit)
  C:\Program Files (x86)\GEOTEC Office (64-bit)
The folder contains the application subprograms of ELPLA: bohr, elpdt, elpgr, elpla, elpls, elpsc, elpsv, ….

Ask 1

Right-click on the application subprograms individually and choose "Run as administrator".

Ask 2
3- When the "User Account Control" dialog box appears, click the button "Yes".
4- After clicking the button "Yes", each subprogram will be run individually.

You need to do this step for all subprograms only one time. Then you can run ELPLA from the Desktop normally.
