Victron Energy Software compatibility
Johannes Boonstra, who you often see helping out and commenting here on the blog, and others have already upgraded their work computers and tested Victron Energy software with Windows 10.
The only hiccup Johannes encountered was that auto-update for VEConfigure didn’t work and he had to reinstall VE Configuration tools to get auto-update working again. Please do the same. Once done everything will work as it should. Other than that there have been no other reported issues.
