Hi Team
we have an existing setup for sql server 2016 and package is available in c drive. Now we are creating new named instance at the time getting error "is not a valid installation folder" how to fix this issue.
we tried copy the files to one drive to another drive still not yet working.
it would help if you can share complete error message.
Also, if you can upload the setup log files to some public location (if possible) it would help in pinpointing the issue.
Read below link to know more about setup logs location.
Hi @Ramakrishna M
Please attach the error logs (Summary.txt file and Detail.txt file).
