SQL 2008 R2 - Is not a valid login or you do not have permission.
To whom it may concern.
If when you are installing ACT! or manually creating the ACT7 instance on SQL 2008 R2 on Windows 8 environment and you receive the error message - '' is not a valid login or you do not have permission - probably the name of your computer and user name are exactly the same.
Change the name of your computer, restart it and the installation will complete successfully.
There is a bug in the SQL 2008 R2 installer program that does not recognize the user's credentials when "machine name/user name" are identical.
I spent lots of hours to figure it out while given free support to a customer.
