Narf_the_Mouse: So far, I've only been able to get Software mode working on Windows 10.

Tried #4, the -glide shortcut; that worked. Not sure how to change the resolution from there, though.

Pseudoman: I think you need to use a glide wrapper, like nGlide, for custom resolutions other than 640x480.

necromorte: Thanks for the link!!

I had the same problem with Win7 64 bit.
it could not find the I76.exe

The solution:
Don't install it in the interstate directory, but in the gog directory.
eg:
not here: C:\GOG Games\Interstate 76
but here: C:\GOG Games

I don't know if this patch solved anything for me. The nitro did not work for me, but I only tried to make it start.
I have to check all the different options and perhaps a fresh install of I76. I will post an update if I made some progress

I tested it with software mode. That just ruined my game. nitro still did not work and also the graphics in the movies is messed up. I did not have this before. This was fixed by just reinstalling the launcher.
For me it works best with the glide option. Nitro works and my and the npc's cars go faster. I can't change the resolution, but that is not a big problem. The game works for me now!

Restarted the whole game and at level 2 it was way too hard to beat Taurus!! Just as I remember when I played this years ago.

hip63: UPDATED! New I'76 Arsenal Launcher with bug fixes

I'76 Launcher v1.5 (without dgVoodoo support)
http://www.gamefront.com/files/16096693/I76_Launcher_v15_Setup.exe
http://www.megaupload.com/?d=E5S2MAJV
http://www.mediafire.com/file/ltrvah62dfl11ut/I76_Launcher_v15_Setup.exe

The purpose of the Launcher is to help players get I'76 and Nitro running with the best performance.

Even though GOG.com did their best to get I'76 Arsenal working on modern operating systems and modern hardware, there are still several shortcoming to game play that GOG.com did not correct. This Launcher is designed to help fill those gaps with the least amount effort possible. (we are lazy, lol)

PLEASE NOTE: It is recommended to set the compatiblity mode for the I76.exe and the nitro.exe to Windows 98 Compaitblity Mode for best results.

You have three rendering modes available:

Software mode
DirectX Mode
Glide Mode

I'76 Launcher v2.0 (with dgVoodoo support)
http://www.gamefront.com/files/20847074/I76_Launcher_v20_Setup.exe
http://www.megaupload.com/?d=3QRWRSID
http://www.mediafire.com/file/yqctgdyq68893jg/I76_Launcher_v20_Setup.exe

This package includes dgVoodoo 1.50 beta 2 Advanced Glide Emulation Support.

The purpose of the Launcher is to help players get I'76 and Nitro running with the best performance and best graphics wih minimal effort.

- - - HOW IT WORKS: - - -

When you start the I'76 Arsenal Launcher, first, it automatically closes the Windows Explorer shell. Why? To prevent graphic problems in the game menu and cutscences such as the "Rainbow Graphics" bug. But not to worry friends, when you exit the launcher, it automatically restarts Window Explorer Shell for you. :)

Also when the Launcher is started, it automatically starts CPUGrabber. CPUGrabber is a CPU Throttling program. Basically, modern CPUs are just to powerful for the old 1'76 engine and this in turn causing issue such as wobbly wheels, bouncing suspensions and issues with the flamerthrower and mortor weapons. The actual setting for CPUgrabber will vary from machine to machine, so you will have to play with it get the right setting for your hardware. The launcher will automatically set CPUGrabbers CPU affinity to a single processor core.

When starting the game via the launcher, it will automatically have it's CPU affinity to a single processor core (the same core as CPUgrabber).

Selecting the Advance Glide Settings button in the Launcher will open the dgVoodoo Control Panel to allow you to tweak the game's glide rendering for the best visuals. Please note these setting only work if you use the glide rendering option. Both Interstate 76 and the Nitro Pack each come with there own dgVoodoo options so they can be tweaked individually.

Enjoy!

PLEASE NOTE: For whatever reason some AntiVirus programs (notability AVG) may claim that the installers contains a virus. I assure you that this is a FALSE POSITIVE. Think about it, would I REALLY want to try to spread a virus though a website that has access to my name, address and phone number via my credit card purchases? I would have to be the all time KING of IDIOTS and while I am human (last time I checked) I am certainly not THAT stupid, lol ;)
