Abnormal return from spawn of GAMS/Base / Unable to display solver matrix

Note: Starting with distribution 22.5 the 64 bit GAMS version can not be installed on a 32 bit operating system. Also the GAMS IDE will pop up a warning, when running the wrong version of GAMS.

You get this error when trying to execute the 64 bit version of GAMS on a 32 bit version of Windows. Unfortunately with older GAMS version ( until 22.4) you can run the setup.exe programm without getting a warning.

The IDE will work as expected, but you will get all kind of strange error messages when trying to run GAMS: abnormal return from spawn of GAMS/Base or (within the IDE) Error=193; Unable to display solver matrix

Solution: De-install GAMS and install the appropriate GAMS Version. If you are not sure whether you have a 32 bit or a 64 bit version of Windows, please click here.
