I have been testing installing and upgrading to GP 18.2 from GP 2018. It immediately comes up and says do you want to upgrade the existing instance of GP or install a new instance. This tells me that GP 18.2 thinks it is GP 2018. Normally you would not get such a choice. Creating a new instance works just fine. However, updating the existing instance does nothing. It does not load the new chunk files nor update the DEX.INI file or any of the files. The best you can do is to select to remove GP 2018 and then run the installation over again. This time since it does not sense an existing instance all proceeds as it should. Has anyone else experienced this? I have had a rush of these due to our payroll clients who need to go to GP 18.2 for their payroll year-end.
