Hi guys. I've been having two different issues with Rex4 with soft clouds boxed edition since i received it Saturday. I'm running Windows 10 64 bit. I first installed it and it started up fine at first. Then i tried to update following the links within the programme it downloaded the Zip file and i extracted the setup file and double clicked on it and got "installation package could not be opened. contact the application vendor" message. i tried to find a solution but with no luck so i decided to remove and reinstall Rex4. I updated Windows 10 first to the recent November patch. and then installed Rex4 all looked like it should and i started REX up, the cool cloud intro came and went then the programme minimised and black screened. I tried the steps from Sundays post about deleting the LocalDB v11 and making a new one first manually then using the batch file in the link, but this hasn't had any effects. i have since tried to reinstall again but Rex4 still isn't working for me. Any Ideas here? Its probably something simple im sure. Any help much appreciated Dave.
