Error of reinstallation - Mailing list pgsql-bugs

Hi there

I uninstalled Postgresql and wanted to reinstall it again, unfortunately, this error appeared after I tried many times. I searched for a solution online, but I didn’t make it. For example, run as administrator, or use the command regedit to delete the relevant Postgresql folder. I hope you can help me, thanks a lot. 

Kind regards, 

Chang
