Look, people write stuff in forums and half the time they write irrelivent stuff that helps no-one. So i'm asking for an honest answer (after looking through the others i doubt i'll get one)

I have recentaly bought sh3, i attempted to install said game and it gets to the end and gives me a "game could not complete installation 1643 (or 1628 i forget)". Anywho when i try to start the game it says "game is not properly installed".

I find this odd as i have installed sh4 and played that to the end, as well as all my other games, which is quite a few. Anywho, its NOT a problem with the disc as i managed to install it on his computer.

I know it makes it hard for people to give me advice as ur not rocket scientists (although u might be), and u don't know what exactualy is going on within my computer..... (such as conflict in files and such). However i was hopinh for a little reply even if its not a dead sert in helping, i would like any advice on how to get the game to install.

(p.s i tried it with two diffrent cd/dvd-rw drives in my computer and still no luck, i have updated the firmware and still nufin).....
so is it possible that there is a common file that may help if i deleted it... or possibly a conflicting program... plz someone reply! (i'v ran the computer in so many modes to try and get it to work and jack happens)

(sorry i blabber on)

Sometimes, it's the CD or DVD burner/player. Not all images placed on the top of CDs/DVDs are balanced. As little weight as the ink may have, if it's thinker on one spot than the rest, it causes the player/burner to wobble a bit. Prevelent mostly in players that spin at or faster than 42X.
It's like having an unbalanced tire that causes your car to vibrate at 40 to 50 mph but not above or below those speeds.
Sometimes, the CD player retainer screws get loose. Listen and hold your hand on the front of the player as it spins when you try to install the game. You may have to become clever and figure a way to secure or dampen the vibration.
I had this problem installing a Corel CD.
What speed does your player spin, and what did your friends spin to?
The thing about installing software is that the CD may not play on a different player than the one use to install it with.

i dunno what cd drive my friend has, but its a customized beast of a computer!, with crazy neons everywhere.... he spends way too much on it.... but anyway i think my cd drive spins at about x42 or sumfin, i can;t remember, but i know its fast... is there such thing as 64? i dunno. I'll try sticking it down abit lol..... mayb lead weights will help?

Thanks anyway

Fancy doesn't mean squat, once you rule out a loose CD/DVD player vibration of the CD/DVD spinning at high speed is the next possibility. If you could get a hold of a slower drive or a burner for a test, (burners tend to be slower)
