Restore msvcr100.dll from the Recycle Bin. The easiest possible cause of a “missing” msvcr100.dll file is that you”ve mistakenly deleted it.

Copy the msvcr100.dll file from the System32 folder and paste it into the SysWOW64 folder. This works if you already have the DLL file in the 32-bit folder (System32) but are having troubles with 64-bit programs accessing it.

The full paths of these folders are C:WindowsSystem32 and C:WindowsSysWOW64. Just right-click and copy the DLL file from the first folder, and then paste it into the second.

Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. This DLL file could be included in one of those updates.

If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible.

Repair your installation of Windows. If the individual troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.

Use a free registry cleaner to repair DLL related issues in the registry. A free registry cleaner program may be able to help by removing invalid registry entries that might be causing the error.

We rarely recommend the use of registry cleaners. We've included the option here as a “last resort” attempt before the destructive step coming up next.

Perform a clean installation of Windows. This will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the error, this should be your last course of action.

All the information on your hard drive will be erased during a clean install. Make sure you've made the best attempt possible to fix the error using a troubleshooting step prior to this one.

Troubleshoot for a hardware problem if any msvcr100.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.
