Which method works best for you, will depend entirely on the root cause of your current predicament. That said, I’ve listed the solutions in order of difficulty and effectiveness.
Run a Registry Scan
The Windows registry is a very important area of your operating system. Essentially, it’s a database, containing various pieces of data, including references to DLL files on your computer. It’s these references that Windows will use, when attempting to locate a specific file, and is where Windows will look, when trying to locate msvcrt.dll.
Unfortunately, the registry is highly susceptible to corruption, resulting in portions of the registry becoming unreadable to the operating system. The end result is a system unable to locate certain key Windows files. Fortunately, it is possible to repair the registry through the use of specialised software, such as Advanced System Repair Pro.

Replace the Msvcrt.dll File
If both method above fail to rectify the msvcrt.dll issue on your system, then I suggest you consider replacing the file altogether. To do this, you will need to download a replacement file, and use that to overwrite the current one on your system.
To do that, follow the instructions below:
1. First, you will need to boot into your computer system as a full administrator.
2. Then download one of the following msvcrt.dll files:
Msvcrt.dll for 32-bit Windows: http://www.mediafire.com/file/v5nkgodg8tttn6y/msvcrt+32.zip/file
Msvcrt.dll for 64-bit Windows: http://www.mediafire.com/file/8hpehef8z3g2qb7/msvcrt+64.zip/file
3. Next, press + R, type C:\Windows\System32 and click on OK.
4. When the System32 folder opens, locate and rename msvcrt.dll to msvcrtBACKUP.dll.
5. Then, open the Msvcrt.zip and click on Extract To.
Note: Step may vary depending on which utility tool you’re using. For this tutorial, I’m using WinRAR.
6. This will bring up the Extraction path and options applet, from here, type C:\Windows\System32 into the Destination path box, then click on OK.
7. Lastly, restart your computer.
If done successfully, you should have a new, working version of the msvcrt.dll file, on your computer. Any and all issues relating to the msvcrt.dll file, should now be solved.
Use Windows CD to Recover File
If you’re on an older version of Windows, such as XP, then it’s possible for you to use the msvcrt.dll file on your Windows installation CD to replace the one on your system.
To do this, you will need to enter the Recovery Console. If you don’t know how to do that, you can find, step-by-step instructions on my post on fixing Advapi32.dll errors.
1. Once you’re in the Recovery Console, you will need to type the following commands, pressing Enter, after each line:
CD System32 Ren msvcrt.dll msvcrtBACKUP.bak D: CD \i386 Expand msvcrt.dll_ C:\Windows\System32 Exit
Note: C: assumes your operating system is installed on the C drive, while D: refers to your primary CD-ROM drive. Both may vary, depending on how you have things setup.
When successfully completed, you should now have the original working copy of msvcrt.dll on your system.
