Try reinstalling the program for to fix this problem.” Any help will be appreciated.” - Krystal M., Australia

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Getting the msvcr100.dll error can be really annoying because there isn’t a lot of information out there to easily fix it. It can be fixed with relative ease if you can follow a few simple steps.


The Msvcr100.dll file is missing or damaged and causes various problems in running software.

Fix The Registry Using A Registry Cleaner

The registry is at the heart of the Windows operating system. It contains configuration records for every component of Windows. This includes software and hardware components. It also contains links between files.

If one of these links is broken or altered, it can result in errors like missing Msvcr100.dll. You can try using WinThruster as your registry cleaner software to fix these links and other problems in the registry. It is an award-winning registry cleaner made by Microsoft Certified developers.

For added safety, we recommend that you make a system restore point before cleaning the registry even though WinThruster already makes a backup of the registry.
