Troubleshooting Common SR1 Installation Errors

Despite being an update, SR1 can fail. Here are the top three fixes:

Error 1: "Missing msvcr120.dll"

• Solution: Install the Visual C++ Redistributable Packages for Visual Studio 2013 (x64). SR1 relies on this runtime.

Error 2: "Help 33 fails to index"

• Solution: Run the Help installer as Administrator. Disable your antivirus temporarily; the indexing engine is often flagged as a false positive.

Error 3: "Numbering still slow"

• Solution: Reset your numbering settings. Go to Tools > Options > Numbering and click "Restore Defaults". The SR1 patch changes default parameters retroactively.
