Rebuilding run-time solution gets "Unknown Error: 20412."


FileMaker Pro


FMP Advanced 11.0v2

Operating system version

Mac OS X 10.6.6

Description of the issue

After updating a FileMaker solution, I usually rebuild the run-time version into the same folder as the previous version to avoid having to populate that folder with support files, e.g., copy 3rd party plug-ins into the Extensions folder.

I just had a rebuild fail near the end with a mysterious error I've never seen before:

"Unknown Error: 20412."

A second rebuild failed with the same error.

Deleting the old run-time folder resolved the error.  My guess is FMP Advanced 11 was unhappy overwriting a run-time solution built by FMP Advanced 10.

Steps to reproduce the problem

I'm uncertain how to recreate this problem because I'm sure FMP Advanced 11 has successfully overwritten other run-time folders created by FMP Advanced 10.

Expected result

Replace the old run-time solution with a new one.

Actual result

(see Description)

Exact text of any error message(s) that appear

"Unknown Error: 20412."


Delete the old run-time destination folder, forcing FileMaker to create a new, empty folder.
