I'm migrating instiki from a WinXP box to a Win2k8 box as well as

Did you do a

   rake migrate RAILS_ENV=production

?

When I run

Rails 2.3.0 not 2.3.1.

instiki.cmd it looks like the app starts up although I did notice it says

The release version is based on Rail 2.3.0.

The development version (which fixes several bugs in 0.16.3) is based on the (not-yet-released) Rails 2.3.1.

 When I navigate to localhost:2500 I receive this
error:

ArgumentError in WikiController#index

RAILS_ROOT: D:/instiki-0.16.3

One option you might try are the instructions here:

   http://golem.ph.utexas.edu/instiki/show/Migrating+to+MySQL

Hmm. Are you migrating an existing installation, or starting a new one? (I assume the former.) They're for migrating from a SQLite3 installation to MySQL. But I suppose they could be equally useful for migrating from one MySQL installation to another. But I'm guessing the problem is simpler than that.
