Unnamed title application

The past few days I've been investigating why a certain application would not function properly in our Windows Server 2008 R2 64bit environment. The result boiled down to two loops being thrown within the application. 1. The Account ID when typed into the prompt was saved into a different code when placed in the settings.ini file. 2. The email functionality for the application required users to be able to write to the c:\program files (x86)\[application name] folder. I think #1 is a result of the client not being programmed to run on a 64 bit OS, but #2 is just inexcusable. Please, please, please developers, stop using program files as your temporary file storage. Why not %TEMP%? Users are not always Administrators in Windows anymore.
