Regional Settings on Server 2012 and Windows 8

We have come across many different errors when users open a SAP file or launch Stadium application on web server. Some of the errors encountered were:

1. Opening a SAP file results in 'The file is not a valid Stadium application file'
2. Users are unable to select Date from the DatePicker control. The display resets to ____/__/__ when a date is selected

Many of these have occurred after migrating Stadium application to Server 2012/Windows 8.

The solution was to apply correct Regional Settings in the server. The steps can be found in Zendesk Knowledge Base article :

Hence, if you have just migrated the Stadium application to a new server, it is essential to check if the above settings have been applied.
