GTA 5 Disc 1 .iso needed(Bought the game)

Yo can someone help me find a gta 5 pc disc 1 .iso file. I bought the game but my disc one got scratched during the installation( Yes im that fucking stupid) and now I'm at the end of the installation and I can't finish it because my disc 1 wont read.

If i hadn't started installing the game I would've just done the digital download from social club but now that I've gone through all the discs and I'm right at the end.

Please could someone find me a disc 1 .iso?

Thank You
