I've had this on 4.5.2 and 4.5.3, on 3 installs on 2 different hosted services. Here's what I do:

The entire Install package is copied to the directory (in 2 cases it was a virtual directory, and in one case it was the root).

Create the database (SQL Server 2005)

Set IIS and user permissions - read write on everything, all directories and files.

Start up the install wizard.

Typical install.

OK on permissions test

SQL Server 2005 database

SQL Server username/password

Connection ok, connected as dbo.

Database is created and updated through 4.5.3 without problem.

host account created without problem.

Now we get to the problem. The module install form. I select NONE of the options. "Links" and "HTML" are selected and disabled, assuming they are required defaults. So with no change, I click Next.

It always gets this:

Error Installing Module(s):
HTML (04.05.00)Error Installing Module(s):
Links (03.03.07)

There is no error message. I can access the database directly. There is no getting past this, as it just returns to the same form. Repeating doesn't fix it. Can't run any portal, of course.

Nothing in SiteLog or EventLog.

Now, in the past, I had to completely wipe the entire thing clean, re-uploadt (90 minutes), create a new database, set all permissions, and try again. After 2 or 3 tries, it succeeds, no explanation. Two different hosting services, so I think the problem has to be in the install process.

How can I get the install to work without this problem?
