People, the problem lies only with the Dawnguard DLC, if you don't believe me, you can open the skyrim Launcher, go to Data Files and untick the Dawnguard DLC. Make sure the save files you will load are Vanilla ones and not Dawnguard ones (still I'm not sure, even the Dawnguard save files could work). You can play as much as you want and you won't get any random CTD (just crashes to desktop without any warning) or Visual C++ Runtime Library R6025 Error. I've found a person describing the problem EXACTLY as it happened with me, take a look (link of his post http://steamcommunity.com/app/72850/discussions/0/864951657875734667/?l=spanish ) : "Hello, after 34 hours of trouble-free gameplay my Skyrim keeps crashing frequently. I have bought and installed the Dawnguard DLC and I was playing all the time with this DLC enabled without any problems until now. I do not have any other mods except this Dawnguard DLC. Yesterday I have decided to do the DG questline and at the Soul Cairn part the problems started to appear. The first crash happened right after Valerica gave me the quest to kill three Keepers. Second one right after turning in this quest and another one after defeating the Durnehviir. From this time the game crashed every minute. I managed to leave the Soul Cairn thinking there was something that caused these crashes but I was wrong. The latest crash was at Winterhold College with 15 minutes since the previous crash. Error message says something about C++ R6025 - Pure virtual function call related to the game itself (judging from the path the message shows) I've been searching on the internet for some solutions but without any success. I have reinstalled my GPU drivers and C++ redist library though both were already at their latest versions. Redownloading the game helped just for a few hours, I have experienced the crash again. My specs: AMD Athlon 64 X2 Dual Core 3800+ @ 2.0GHz 4GB Ram GeForce GTS250 512MB Windows 7 64bit Direct X 11 I can run the game smoothly at medium/high setting so I guess my specs are okay for this game."
