Hello,
I just got this error after reinstalling Win10 202H (reinstall from scratch). Winbox 64/32 bits 3.27.
I clear cache from the menu option, also user temp dir and system temp dir... search the forum but seems its not a very common problem.
I have an admin user with admin rights, and a normal user with normal user rights that I use every day.
If I run winbox64 3.27 from this normal user, the winbox config files generates themselves: sessions, sessionpath and Addresses.cdb... in root of my drive E (dont know why here) with no addresses/passwords, empty.
Then if I import a .WBX file with all my routers data I see them listed but any of them that I try to connect gives routeros.jg error.
If I close this winbox and reopen, non of the addresses lately imported appears... like it is not saving or cant access default directory winbox is used to (I mean: C:\Users\USER\AppData\Roaming\Mikrotik, there I used to see this folders in my old windows installation, but now they wont generate there, insted ther appear in E:\)
If I open winbox64 wiht administrative rights, there everything works fine like it used to, and winbox config file generates and works where it should (mean C:\Users\admin\AppData\Roaming\Mikrotik\winbox)
I also tried clearing cache within winbox.
Also tried disabling windows firewall, but no difference.
Also checked user directory permissions, correspond to the user being logged. (will try creating a new user)
So, any idea? what does it mean "No roteros.jg found" its like the Windows IRQ Interrupt hokus pokus? :-p
PS: also test it with winbox 32bits, the only difference is that it generate the config/session files in C:\
