Hi everyone, For some reason Dev Mode will not start. Un-installed and re-installed and same deal. I click on the icon and there is a blink then nothing. Stays at the start menu. So, I hunted around and found out that some W10 updates mess up the installation. >>>>Fixed it.This may help others. Tim has a post in the forum... https://forum.studio-397.com/index....0-removes-runtimes-after-major-updates.58239/ Reinstalled the vcredist executables in the _CommonRedist folder....They were somehow unistalled via an W10 update maybe??
