These are the Grand Theft Auto installation instructions.  If you are installing Tombraider try here.

Initial use of Glidos requires a number of steps.  Click on the list items below in turn to see detailed instructions.  You will save yourself a lot of problems if you read through these instructions thoroughly.  If you run into any problems try the support page.

The last step is not essential, but thoroughly recommended.

Install Grand Theft Auto

The first step depends on which version of Windows you have.  If you have Windows NT, 2000, or XP then the first thing to do is download and install VDMSound.  It will make sound work for all your old DOS games.  Its free; it is daft not to use it.  Here is where to get it from. 

I obtained my copy of GTA from Sold Out Software.  Their CD installs a DOS version and a Windows version.  It's the DOS version you want.  It will install to C:\GTA\gtados.  Under Windows 2000 and XP, GTA has problems accessing the CD, so you need to apply the NO-CD patch.  The patch can be found here.  It's an archive; unpack it, copy the file GTAFX-C.exe into the C:\GTA\gtados folder and double-click it.

Download and install Glidos

Just go to the download page and click the link to the latest Glidos_vXX.exe file, save it to disc and double-click it to start the install process.  The installer will put a shortcut on your desktop, unless you tell it not to.  Under Windows NT, Windows 2000 or Windows XP, you may have to install Glidos using an account with administrator privileges.  I haven't experimented with this yet, so I'm not sure.

Run Glidos and play Grand Theft Auto with high-quality graphics (Important)

There's an oddity to running GTA.  Double-click the Glidos shortcut on your Desktop, select Grand Theft Auto and click the "Start game" button.  A DOS window will appear  Wait a few seconds, and press the ESC key; then the game will start.  You can use the "Adjust" button to select full-screen mode and change the resolution, but only while not running the game.  Don't use fullscreen mode until you've tried it in windowed mode first; if there are problems, it is easier to see what is going on in windowed mode.

Under Windows NT, Windows 2000 and Windows XP you may need to run Glidos from an account that has administartor privileges.

Buy Glidos to get rid of the spinning logo

I like to make the first few levels of each game free, but sorry it wasn't possible for GTA.
