Good evening,

I'm kindly asking for your help on an issue that I face as I have installed GAMS v.24.8.5 in a Windows XP 32 bit machine.

When I press "Run GAMS" on my model, I get the following message:
"Error: Unable to start process
Error 193: %1 is not a valid Win32 application"
while this is not happening on a Windows 10 computer.

While searching on Google, I found this solution provided by Microsoft (as other programs appear to have this problem) : ... essage-whe

but ir requires to make some changes on Windows Registry and especially on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\.

Could you please inform me about the name of the relevant with GAMS services on Windows Registry in order not to make a mistake while making changes or alternatively on how to resolve the issue if you know another way?

Thank you very much in advance!
