how to install new userman i am using router os 4.6

Download the file from mikrotik.com/download, transfer to the router using ftp (easier for me compared to the netinstall) and reboot the router and it will be automatically installed or upgraded.

UM4.6 test is not yet available. If you must use UM, downgrade to ROS4.5 and download and install UM4.5.
When UM4.6 is ready, download link will be posted here: http://forum.mikrotik.com/viewtopic.php ... 76&start=0

i am install usermanager 4.6 but old usermanager data base errer colum 19 etc any solution thanks

you have to download the UM 4.6 test version, then go to the folder with all the packages, rename the UM test version with the actual name of the usual version, then delete the normal and paste the test version with the name of the normal UM and then you can work normally as you were working with the previous one.
That's how i did it and it worked fine
