After using AdvanceSyetemCare utilities to clean their PC a customer reported that TaxCalc (network version) would not start.
Further investigation showed that the PostgreSQL service (The database back-end) had been disabled. This meant TaxCalc would not work as it had no way of writing to or reading from the database.
To resolve this issue
Please note: If there are more than one instance of Postgres, repeat these steps for each one.
The Postgres service now needs to be started.
If PostgreSQL does not start, it is likely that another module of AdvancedSystemCare (Empty Folder Scanner) has removed empty folders in the database structure. Removing these folders means that the database engine cannot start as the structure needs to be complete. In this case, call the Support team who will try and assist you in rebuilding the folder structure
