Since, the CMS Assessment tool was released two bugs have been reported.
The first, is a bug in the Excel spreadsheet used to display the results. There's an error when running on non-English versions of Excel. After hitting the “Load Analysis Results” button, you get this error. Below is an example of what this error looks like in German:
Die PivotItems-Eigentschaft des PivotField-Objektes kann nicht
A simple workaround is to switch to the language Excel is using to English.
The 2nd bug is a timeout error when running an analysis of the large CMS repositories on .Net 1.1.
We are testing fixes to both of these now and will release an update in a few weeks.
