Activating Chart of Account

My company is a USA non-profit so I want to use the US COA for a nonprofit company.

I installed Front Accounting 2.3.20 via Softaculous. During the install it did not give me the option to select a different Chart of Accounts, nor did it give the option to create additional companies.

After the install I went to Setup/Install Charts of Accounts. I clicked the Upload and Install icon next to the US COA for a nonprofit company. I'm guess the upload and install worked because the icon is no longer visible and a red X is in the last column.

However, when I look at the general ledger accounts (Banking and General Ledger/GL Accounts) the accounts showing are not the for the US COA for a nonprofit company.

The wiki on Install/Activate Chart Of Accounts (https://frontaccounting.com/fawiki/index.php?n=Help.InstallActivateChartOfAccounts), shows step 3 instructions as "Select the chart of accounts when you create a new COMPANY."

I've tried creating a new company, but during the process I'm not given the option to create a new username and password for the new company. When I try to login using the SuperAdmin username and password, it doesn't work.

My question is: how do I get the US COA for a nonprofit company to work with an existing company or how do I create a new company that I will be able to log in to.

Thanks!
