When installing to SQL Server 2008 all steps are green (Good) until the one detailing:

Schema DropColumnSQL ( mantis_tokens_table )

This shows in error, detail:

"BAD
ALTER TABLE mantis_tokens_table DROP CONSTRAINT
ALTER TABLE mantis_tokens_table DROP COLUMN timestamp
SQLState: 42000 Error Code: 102 Message: [Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near 'CONSTRAINT'. "

This is preventing me installing the system to evaluate it for use.

This is not an upgrade - I have seen other issues for upgrades mentioning similar issues, but this related to a new installation.

PHP, etc is set up fine on IIS.

Tried a few times, and same each time.

Also; Ran with "Print SQL Queries instead of Writing to the Database " checked - the generated SQL does not run on MSSQL.

Attached screenshot of issue.
