We are having a driver INF file inside that there is a coinstaller session, which is showing the error "Found legacy AddReg operation defining co-installers (CoInstallers32)" while doing the WHQL testing in latest win11 OS.
For all the previous OSs, it was working fine and not throwing this error but only in latest Win11 OS its failing
Win 11 Version : Win11x64(22H2) 22621.900.
How can I fix this issue?
What are the possible alternatives to support DDInstall. co-installer in INF file?

Universal. My Target Platform isDesktop. How do I workaround this issue? -

Kevin Tharp 35 Reputation points2023-04-28T15:40:48.4933333+00:00 I am encountering the same issue, and I do not currently need Windows 11 so disabled the check against those versions and am still getting the same error message.
