Default User Name

I am using ACT Pro V18 on Windows 7 OS.

After backing up the Database, a Fresh Reinstall of Windows

and a Fresh Reinstall of ACT Pro v18 was completed.


Each time Restore is attempted, the message "Act can not Authenticate User" pops up.

I did not use a password with the backup


I have noticed ACT 18 show "not responding" on some attempts to restore from the Demo

database;  A new database was created and it opened to Restore but did not recognize the

User Name.  I'm apprehensive to uninstall and reinstall because in the past I had error messages

that a previous Instance of SQL was found.

Thanks for some guidance.

Re: Default User Name

Question, are you sure you are placing the correct user with you created the database?


There is no default user for the Act! Database. - You must remember the correct user to be able to do the restoration and open your database again
