I just found what seems to be a serious problem and I am not able to figure if it is related to my own installation or not.
After I installed Physics 426 (Published on Sept 17, 2019) using the Maple GUI install button (which now works for my PC), I found I am not able to integrate basic things.
It seems to affect int when using some build in function with definite integration, but it could be others also. I need to test more.
Could someone see if they get same problem as well?
Could also someone please remind me of the library commands to issue in order to remove current Physics version 426 and install earlier Physics version package, say 425, or any other version, so that to see if this is related to version of a physics package or not?
