Re installing C+++ will not help, re installing FF14 ARR will not help, updating your graphics driver or roll backing to an older driver won't work ether. The R6025 runtime error is a corrupted code error, usually everything that has been listed will fix the problem but people have tried all the solutions I listed, people who've bought a brand new computer have even got this error.

In short this is a bad code on SE end, this problem has been around since the start of live and there's even 2 topics one with 35 pages and one with around 5 pages, SE has chosen to ignore that this is an actual problem.
