I tried upgrade tool, but text not changed other than "initiliazing". Error continues.
I tried running setup.exe and setup installation finished successfully. But I can't log on.
I repaired SEPM from add/remove panel. But no change on errors.
I restarted server many times whenever I made any change...
There is a backup old and faulty. I removed completely, installed SEPM and restored backup. But error comes again. Can I clean errors from backup? How can I track errors? How can I restore only pc, policies and settings without errors?
