Answer: There are a variety of issues that may be causing you to have this Unhandled Exception problem. Please read through the list below for some possible solutions.
--If cheat codes have been used, and you have saved your game after the cheat code has been used (even if you disabled the cheat before saving), there is a strong possibility that the data used in that save game has become corrupted; this will sometimes cause an Unhandled Exception error if you try to load the game. We recommend that if you feel it necessary to use cheats, you should not save the game. These cause a number of unpredictable results, and basically take the game out of our control. Delete any save games that have had cheat codes used in them.
--A third-party feature pack for streaming video files, called "Nimo Codec Pack," has been known to cause a number of different problems when trying to install and run
GTA: Vice City. If you do have this installed, we recommend uninstalling the Nimo Codec Pack, then try to install the game.
If you are certain you do not have the Nimo Codec Pack installed, and you have not used any cheat codes while loading or playing your saved games, please try the following solutions in order:
1.) Completely uninstall the game.
2.) Delete the main default game folder: C:\Program Files\Rockstar Games\GTA Vice City
3.) Delete the default installshield folder: C:\Program Files\InstallShield Installation Information If you do not see this folder then do the following:
Open windows explorer, go to VIEW or TOOLS, FOLDER OPTIONS, VIEW then click on the circle next to show all files. Press APPLY this then press OK you will now see the folder (it is grayed out) .
4.) Delete the save game folder in your 'My Documents' folder called 'GTA Vice City User Files.'
5.) You now will need to do a registry clean to make sure no game files were left during the uninstall. The easiest way to do this is to download a program called Regcleaner. You can download the program from here:

6.) Reboot your system.
7.) Do a scandisk and quick defrag of your hard drive.
8.) Lower your desktop resolution for troubleshooting purposes. The game is best installing and playing the game. Go to Start, Settings, then Control Panel. Double-click the Display icon then, click the Settings Tab. For the Color Palette setting, select 16-bit High colors. (Do not use 24 or 32 bit color modes) For the Desktop Area, set it to 800 x 600. Click Apply, and restart the system if prompted.
9.) Double check your monitor settings:
A.) For Windows 9x/ME Users: Check your monitor settings by Right-clicking on the Desktop and choose Properties from the menu. Click the Settings tab, then the Advanced Properties button. Click the Monitor tab (this may say ´Unknown, Standard or Default´). Click the Change button, and after Windows builds the driver information database, select the proper monitor type (Plug And Play is usually the correct choice; check with your monitor or system manufacturer if you are unsure). Click Apply, then Ok or Close, and restart the system when prompted. Make sure only one monitor is listed and not two. Remove any other ones listed that are not the true monitor you have connected to your computer now.
B.) For Windows 2000/XP Users: First begin by right clicking on your desktop where there are no icons located and left click the Properties option. Select the Settings tab. Toward the bottom you will see a button labeled ´Advanced´. Hit that button, then select the Monitor tab. Located in that screen is a ´Properties´ button. Hit that button, then select the Driver tab. Hit the ´Update Driver´ button located in that column of buttons. The ´Hardware Update Wizard´ will now open.
On the first screen of the Wizard, there are two options that can be chosen by placing a bullet next to the selection. The default option is ´Install software automatically (Recommended)´. Please change that to the other option, which reads ´Install from a list or specific location (Advanced)´ by clicking on the sentence and placing a bullet there. Now hit the ´Next´ button.On the next screen, the Wizard will ask for your search and installation options. The selection defaults to ´Search for the best driver in these locations. ´Please change that to ´Don´t search. I will choose the driver to install´ by placing a bullet next to that option. Hit the ´Next´ button. If the Plug and Play option is there, please click on it and then hit the ´Next´ button. This will change your monitor setting to Plug and Play. If the Plug and Play option is not there, then please uncheck the box that says ´Show compatible hardware´. This will change the screen slightly to show a Manufacturer´s column, which you should change to (Standard Monitor Types). You may need to scroll up or down to do so. To the right of that, there will be a Model column. Once you have selected (Standard Monitor Types), you will now be able to choose Plug and Play under the Model section. When you have done that, please click the ´Next´ button. This will change your monitor setting to Plug and Play.
10.) Close or disable all background programs running including anti-virus, scanner software, online chat software & direct cd type programs.
11.) Reinstall GTA Vice City, then start the game.
SPECIAL NOTE: FOR NVIDIA CARDS
This error has also been fixed by turning off the antialiasing feature in the GeForce Properties window. To do this:
--Enter your Display Properties menu for your GeForce Card, and change the "Intellisample" settings to "Application." To do this:
1. Right-click on your Windows Desktop, and select "Properties" from the drop-down menu.
2. Click on the "settings" tab, found near the top of the Display Properties window, then click on the "Advanced" button.
3. Click on the GeForce FX tab near the top of the screen. This should open up a window displaying settings for your particular GeForce card. If a side-menu does not appear, click on the small green button on the left hand side of the window; a smaller window should appear on that side.
4. Click on the "Performance & Quality Settings" option.
5. On the Antialiasing Slider, click and drag the slider bar all the way to the left hand side to disable the Antialiasing. Click "OK" twice to close the windows.
