In other cases, the setup fails after the installation is completed, during the first run of the program. One possible error thrown is:
2021-01-26T22:20:14 Master DB connection string: Provider=MSOLEDBSQL;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=master;Data Source=(localdb)\IpposnifSql2016Instance 2021-01-26T22:24:38 ERROR: -2147467259 Unable to complete login process due to delay in opening server connection 2021-01-26T22:24:40 ERROR: 3704 Operation is not allowed when the object is closed.
In these cases, the solution is to switch to a different version of SQL Server, like the Microsoft® SQL Server® 2016 Express, that you can download from here. After you have installed SQL Server Express, before starting Ipposnif, edit the file C:\Program Files (x86)\Ipposnif\ipposnif.ini Change the data source from:
where myServerAddress is the name of your PC. Save ipposnif.ini and run again Ipposnif.
