Hi i am trying to up a version of a project to 4.25 , but when I try to open it , I get the above error. I downloaded the file and went to paste into sys 32 folder , but it says it is already there , any ideas? thanks
So by running the engine first , it got around this , now at 96 percent loaded ,it stopped and says the substance graphs need to be updated , would you like to do this now? I clicked “yes”.
Hey I have the same problem. I found an explain of missing .dll but the link to download is not available.
