I'm trying to set up a test server to prepare for our upgrade on my local workstation and am experiencing unexpected behavior in the install.

I'm doing a fresh install of 7.3, and on Step 8 ("You may now proceed to the next step to create all of the necessary database tables"), when I click the "Proceed to the next step" button, it advances to the next page (createtable.php) and all it displays is "Failed to write config:" with no additional information.

I've verified all the permissions are correct, I received no errors during any of the checks, and all should be fine.

This is a Windows XP Professional machine though, running IIS and PHP 5.6.2. The one thing that was "odd" about this install is that I was using an off port for IIS. But, I changed everything back to port 80 and still get the same issue.

Granted this isn't a show stopper, I was just wanting to get familiar with the 7.3 before upgrading due to the fact that we have hundreds of users using our forums for support, but I thought I'd bring this to attention.

I'm going to create a FreeBSD VM and see if it performs differently on that, than locally installing it on my XP Pro workstation. I'll report the results of that here.

When I created a FreeBSD VM, installed Apache/PHP, etc. on it and then installed the UBB from scratch, I didn't have a problem.

One thing I noticed though was that when doing the install on FreeBSD, it populated the path and URL boxes, whereas on the Windows installs, I had to enter them.

I hope this may have been an issue with Windows XP, as opposed to IIS/Windows in general. The disposable FreeBSD virtual machine is ok to test with, but our production server that will be upgraded is running on Windows Server 2003 with IIS.
