Answer:

1. Windows - Foxhound works with target databases running on other operating systems but the Foxhound engine itself only runs on Windows, and has been tested on Microsoft Windows XP SP3, Vista SP1 and Windows 7.

2. ODBC - Foxhound itself uses ODBC to connect to your target databases. You don't necessarily need ODBC installed on the servers running your target databases, and you can specify DSN-less connections for Foxhound by using the "String" tab on the main menu page.

3. Firefox or IE - The Foxhound client has been tested using Mozilla Firefox 3 and Microsoft Internet Explorer 8.

4. JavaScript - Foxhound needs "JavaScript" or "Active scripting" to be enabled in the browser; here's how:

Firefox 3: Tools - Options - Content - check "Enable JavaScript"

IE 8: Tools - Internet Options - Security - Local intranet - Custom level... - Scripting - Active scripting - check "Enable"

6. SQL Anywhere 32-bit version 11.0.1.2276 or later for Foxhound - Foxhound works with target databases using 5.5 to 12 of SQL Anywhere including 64-bit versions, but the Foxhound engine itself needs the x86 version of SQL Anywhere 11.0.1.2276 or later to run.

7. SQLANY11 - The delivered *.bat files expect that the SQLANY11 environment variable points to SQL Anywhere 11. If that is not the case you may have to modify the *.bat files. Here is the default setting on Windows XP, Vista and Windows 7:

SET SQLANY11=C:\Program Files\SQL Anywhere 11

8. FOXHOUND1 - The delivered *.bat files expect that the FOXHOUND1 environment variable will be created by the Foxhound installation (which will happen by default). If that is not the case you may have to modify the *.bat files. Here is the default setting for Windows XP:

SET FOXHOUND1=C:\Documents and Settings\All Users\Application Data\RisingRoad\Foxhound1\

SET FOXHOUND1=C:\ProgramData\RisingRoad\Foxhound\

9. Disk space - When re-installing or upgrading Foxhound, 60% or more extra disk space may be required during the post-setup process. The "60% or more" figure applies to the amount of disk space occupied by the existing Foxhound installation, not the total used disk space on the drive.
