Installing retail version on 64-bit systems

The official 16-bit installer will not run on 64-bit systems.
A German website has a custom installer here. It also includes and installs the patches, up to the Gold Edition.
winevdm can also be used.

Manual installation
  1. Create a folder where the game files will be located.
  2. Copy all files and folders to it, with the exception of the DEMO and DirectX subfolders and the setup.exe file.
  3. Create a .reg file, edit it in a text editor to include the data below (note that the path to the game needs two \ characters), and run it as administrator:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\I76.exe]


[HKEY_LOCAL_MACHINE\Software\Activision\Interstate '76]

[HKEY_LOCAL_MACHINE\Software\Activision\Interstate '76\1.06]

Textures are "flipped" with other textures in Glide mode[6][7][8][9][10]

This is a bug in some Glide wrappers. Reduce the texture memory to 2 MB to bypass this.
If running a real Voodoo card, add the following to a batch file followed by the game's executable:

Game crashes after mission 12

Official response from Activision representative[11][12]
This problem can be fixed by retrieving the I76shell.dll from the 1.06 or 1.08 patch for the original I76 W95. Do not install the 1.06 patch to the Gold Edition! It will crash. Instead, extract the 1.06 patch to a new folder. Copy the I76shell.dll file to the Gold Edition directory. Only 1 file will be replaced.

I tested Gold i76 using the i76shell.dll file from the 1.083 patch. It worked! I was able to get into the 13th level without a page fault crash. Be sure to back up the original .dll file though before doing this. The Gold edition will crash on Instant Melees with 1.08 .dll file installed. I would only use the 1.08 file temporarily for the purpose of gaining access to the 13th level.
This can be simplified by renaming the patch .dll to I76shell_1083.dll ( version already includes it), then using the following batch scripts to enable and disable the fix. Name them as such:
Batch file contents


@echo off
if exist I76shell.bak goto error
ren I76shell.dll I76shell.bak
ren I76shell_1083.dll I76shell.dll
goto fix

echo Mission 13 Fix already enabled! If you are experiencing crashes in
echo melee or other single player missions, run RevertM13.bat instead.
goto end

echo Mission 13 Fix enabled. Run RevertM13.bat to disable.
goto end



@echo off
if exist I76shell_1083.dll goto error
ren I76shell.dll I76shell_1083.dll
ren I76shell.bak I76shell.dll
goto fix

echo Mission 13 Fix NOT enabled! If you are experiencing crashes in
echo mission 13, run EnableM13.bat instead.
goto end

echo Mission 13 Fix reverted. Run EnableM13.bat to re-patch.
goto end
