A couple of days ago, I downloaded "The Day of The Tentacle", I installed it (including the patch), but unfortunately it does not run on my PC. I reinstalled it 2 times even and nothing.

When I load the game I get a window that says that the game stopped working and that windows is looking for a solution but in the end I have to proceed to close the program.

I updated I do not know about GOG.com and still nothing.

I have windows 7

Can someone tell me why the game does not run or how can I fix it?

Did you try running it in Compatibility mode for a previous OS version (like WinXP)? Did you install as admin? Are you using Galaxy (your post is unclear on that)?

There's a couple of suggestion here for you to try:

Yes I did but still see the same message I mentioned earlier. Maybe it's the video card ?, I tried to install the game on a friend's computer and there runs smoothly

Could be. We'd need more info on your computer's specs to be able to suggest anything. As well, how close is your friend's PC specs to yours?

Maybe the only difference is that the windows it has is 64 bits and the mine is 32, is it because of that?

Probably not. From what I see on pcgamingwiki, the game is 32 bit only. How much RAM do you have?

512 I know, sucks
I had no problem playing monkey island II and Lesuit Suit Larry 7

The Remastered version requires at least 2 GB of Ram, according to the system requirements:
