Installation failed when trying to do that

Getting installation fails error, and see “specified account already exists” error message after going to check log file.

Hi,

Have you installed community edition previously or are you installing for first time

it’s the first time I install the community edition.

In rare cases, the .msi installer can fail with the error “The specified account already exists”.
Microsoft recommends running their fix-up utility and then reattempt the installation.
