So I came across this recently and thought to share it with you guys.
First of all, exit steam completely. If you’ve closed it, check if it’s in the system tray and if it is, exit from there as well. Now, fire up Windows Explorer and go to where steam is installed on your computer. In my case, it was in the default installation directory (C:\Program Files (x86)\Steam).
So I had this problem today. Well to be honest, I had this problem before as well but I decided to fix it today. Earlier today, I upgraded to Windows 8.1 and I was hoping that the upgrade would resolve this problem. Well, it didn’t. After surfing through the web, I found the solution. So, here it goes:
First of all, you need to be in safe mode. Open the charms bar, click on the power button, hold the
shift key and while you’re holding it, click
"Restart". This will restart Windows in troubleshooting/recovery mode.
So I found this error when I started Lotus Notes this morning. After looking through some forums, I found that I needed to re-install Microsoft Visual C++ 2010 (Redistributable) from here.
This error is usually caused by C:\Windows\System32\MSVCR100.dll being corrupted. Reinstalling VC++ fixes it.
