MVP 2023 Ausman Posted August 19, 2019 MVP 2023 Report Share Posted August 19, 2019 fbojan, Flex is heading into explaining that you have fallen into the trap of "always having the latest", when in fact if it isn't broken, don't change it! (This is the reason why the Vision system has Version Swapper, but such a thing doesn't exist for U90.) You need to use/download the U90 version you wrote the original program with and also use that to change the OS to the correct one. The download area lists these under Previous Versions. Many people have an area of their program that specifies exactly what they used at the time. Some have it showing on screens, some in a hidden location that is consistent b/n all jobs. cheers, Aus Quote Link to comment Share on other sites More sharing options...
fbojan Posted August 20, 2019 Author Report Share Posted August 20, 2019 Ausman, I already did it. I just wanted everyone to know about the problem. Thanks. Quote Link to comment Share on other sites More sharing options...
