Is SL Dynamics 2015 cu2 compatible with Windows 11? looks like the software is installed correctly. But when I try to login to the company, it pops up twice and says incorrect company, user id or password. I have tried several accounts that work on other computers. All give the same error.
Mark's answer is correct, it should work but it isn't a supported combination since Microsoft doesn't check compatibility for software versions they no longer support. Having said that, I have a test SL2011 setup on Win 11, I'd expect that SL2015 also works. Check the usual causes of this type of error.
Certainly not supported, was released long before Windows 11 was released. The only officially supported SL version is 2018 CU8. Having said that, I have at least one SL 2018 client running on a previous CU with Win 11 on at least one workstation and not having issues. No experience with Win 11 and SL 2015.
