Update: This issue is resolved now. You need to regenerate your license and it should work.
I have installed Business Central On Premise and uploaded over DEV license. Unfortunately the license did not work and I keep getting the below error
I am getting the same error on the Web Client. Initially, I thought it may be an issue with the license or how it was generated but a quick search found the below twitter post which mentions it is a known issue and they are working on it.
But the question is how do I access the client now, so I tried to upload the license which I found on the DVD in the below path and the same license file (Cronus.flf) is also located in few other folders on the DVD, but none of them worked.
RoleTailoredClient\program files\Microsoft Dynamics NAV\130\RoleTailored Client
The license we need in this case is not Cronus.flf but Master.flf which is located in the SQLDemoDatabase folder. This let me login into Business Central Web Client and RTC. I hope the DEV license error will be resolved soon.
