A common publishing error found when first publishing a report or when starting from a new computer might be something like the following:
An error occurred when attempting to publish the report. The error is as follows: PDF header signature not found. PdfFile object length: 0.
This is usually the case when your computer does not yet have Adobe Reader installed, or the required browser add-ons to enable opening PDF files.
To resolve, simply download and install the free Adobe PDF reader and try it again.
Here’s a quick-link if it helps: ADOBE READER
