1. Then after installation you should manually place a copy of your licence file renamed if necessary to LICEN GEM into your GEMPACK folder 2 1 3 Where to install First decide where to install GEMPACK bearing the following in mind e The ideal plan is to install GEMPACK in a folder C GP to which the user has read write modify access e If you have another or earlier release of GEMPACK already installed in C GP you should probably leave it on your hard disk until you have successfully installed and tested Release 11 0 in case an unexpected problem occurs You should rename the directory containing the previous release so you can install Release 11 0 of GEMPACK in C GP For example if you currently have Release 9 0 GEMPACK in C GP rename that directory to say C GP90 and install Release 11 0 into C GP If you use the same GEMPACK directory as before other GEMPACK related Windows programs such as RunDynam and RunGTAP will automatically use the latest version of GEMPACK e It s best if both the GEMPACK programs and the user s model files are stored on a local hard drive not a network drive e The name of the GEMPACK directory should not contain Chinese or other non English characters or parentheses Also it s best to avoid extremely long folder names See section 7 1 for more details 2 1 4 Notes for IT support You can install GEMPACK as Administrator and run as Limited or Standard user as long as permissions are s2. administrator level account you will be prompted for an administrator password during this procedure For users of Windows XP you must be using an administrator level account when you begin this procedure Right click on Computer Windows 7 or Vista or My Computer Windows XP From the right click menu select Properties then click on the Advanced tab This brings up the System Properties dialogue window click on Environment Variables to bring up the Environment Variables dialogue window Notice that the top half of the window contains user variables the bottom contains system variables 2 Edit the system Path variable and add the GEMPACK directory noting the following Entries must be separated by a semicolon New entries may be added between any existing entries however we recommend adding to the beginning of the Path For example suppose your GEMPACK directory is C GP then the system path should look like C GP C mingw w64 SystemRoot If you have a previous GEMPACK directory on the Path delete it and add the new GEMPACK directory to the beginning of the system Path 3 Add anew or edit the existing system environment variable GPDIR to have value set to the GEMPACK directory This must be the same directory you added to the beginning of the system Path in the previous step 4 Click on the Ok button to accept these changes to the Environment These changes will take effect when you next start a program or open a new DOS box Tes

4. just after installing GEMPACK on a PC running Windows Vista or Windows 7 a warning screen appears titled Program Compatibility Assistant and announcing that This program might not have installed correctly You are offered two options a Reinstall using recommended settings or b This program installed correctly We believe that the warning is needless and that you should click This program installed correctly 2 2 2 Source code only If an error occurs If an error occurs during the BuildGP process you will be told the name of the procedure when the error occurred We suggest that you note this name on paper then exit from BuildGP Usually an Error log is shown This should give you some idea what is happening Possible Checks and Actions to try e Check that there is plenty of room on your hard disk If not you will need to delete some files to create space e Check that Fortran is installed and on your path see section 2 1 5 e Check that the name of the GEMPACK directory does not contain spaces or Chinese or other non English characters See section 7 1 11 GEMPACK user manual e Install again from the CD Or you could try re running just the final BuildGP stage To do this open a DOS box in your GEMPACK directory and type BuildGP Check the GEMPACK directory and compiler choices then click Start Build e If an error reappears please notify support gempack com If an Error log has been created p

BLO generated programs and SAGEM EXE may require an Introductory licence if they are used with a larger model The model size limits are set out in Chapter 62 Versions of TABLO and GEMSIM programs must match exactly Hence do not send GSS GST files generated by TABLO to others the GSS GST files would only work if used with the right GEMSIM version that matched your TABLO Rather send only the TAB file then the recipient can use their matching TABLO and GEMSIM programs 2 8 Manually setting the PATH and GPDIR For GEMPACK to run you must make sure that the GEMPACK directory usually C GP is on your PATH and that the Environment variable GPDIR is set to the GEMPACK directory If you did not allow the installer to make changes to your PATH and the Environment variable GPDIR see section 2 2 you must make the required changes yourself as described next 2 8 1 Checking and setting PATH and GPDIR The usual method to change the PATH and set the Environment variable GPDIR is by editing the System Properties The important changes are that e the directory into which you installed GEMPACK the GEMPACK directory must be on the system Path e the system environment variable GPDIR must be set equal to the GEMPACK directory You will need administrator access to make these changes Follow the steps below to check that the installer made these changes or to make them yourself 1 For users of Windows 7 or Vista if you are not using an
