I found the solution to the SWAT 3 Game of the Year launch error, DirectX error DDERR_Generic.
The solution is a three step process:
Step 1: Download and install the new SWAT 3 Last Resort mod software http://www.swat3lastresort.info/
The SWAT 3 Last Resort mod software greatly enhances the video game's video and audio qualities/ resolutions;
Step 2: Change the game's compatibility settings to Windows XP Service Pack 3 option To do this, you have to implement the following steps:
(1) Look for the SWAT 3 Game of the Year desktop icon on your computer desktop;
(2) Right mouse click on it to open a menu;
(3) Select the "Properties" option at the bottom of the menu by scrolling down to it either by moving the mouse cursor downwards until it is pointing directly at it, and/ or by using the down arrow button on the keyboard to move the option selection bar to it;
(4) Left mouse click on the "Compatibility" option tab;
(5) Left mouse click on the "Run the program in compatibility mode for" checkbox to enable a grey tick mark inside it;
(6) Select the "Windows XP (Service Pack 3)" option in the drop-down menu under the "Compatibility mode" section;
(7) Left mouse click on the "OK" button on the bottom of the SWAT 3 Game of the Year "Properties" windows dialog box.
Step 3: Run the game as an administrator To do this, implement the following steps:
(1) Left mouse click the "Run the program as an administrator" checkbox to enable a grey tick mark inside it;
(2) Left mouse click on the "OK" button on the bottom of the SWAT 3 Game of the Year "Properties" windows dialog box.
The SWAT 3 Game of the Year video game should be able to start and run properly after taking action on the above corrective/ remedial troubleshooting steps in a sequential order.
Perform the first step first, then perform the second step, and finally perform the third step, in order to fix the DirectX error "DDERR_Generic".
