Clarion.asl.dllIf this is the same error I had (installing C12 PE on a fresh Windows 11 Virtual Machine for testing) I suspect it’s because the Clarion installer does not trigger the install of the required VC Redistributables. Instead of trying to figure out which ones to install, I first installed the latest C11.1 PE release, which did install the VC files, and after that I was able to install, run, and register C12.
Good luck.
