"The file is not in a Recognizable format" when opening any report caused by code production problem in Controller 10.1.384 and earlier.

Technote (troubleshooting)


Opening any Report from either Controller or Excel returns an error.

For example, user launches Controller, and then logs out. Then user launches Excel, then logs into database (via excel link). User selects "Reports > Open Report" and chooses a report. User clicks "Open". User receives error.

Problem can also appear when user uses "Reports - Create" functionality.

Problem may appear to be intermittent, because it may only occur if Controller/Excel is launched/logged-onto in a specific order/sequence.


The file is not in a Recognizable format

Alternatively, the user may see the following error:
