Error 53 when creating PDF (file not found: gsdll32.dll) - module modGsApi, procedure CallGS, line 5

Since I upgraded to 1.x, I'm getting the following error when I try to create a PDF from a Microsoft Word document.  It doesn't happen all the time, but it is consistent.

Here's the text from the ERR file:
