Here is the solution I found:

How to fix the missing MSVCR711.dll problem

You can find MSVCR71.dll file in following location of your installed SQL Developer 2.1 directory:

sqldeveloper-2.1.0.63.10\sqldeveloper\jdk\jre\bin\MSVCR71.dll

Based on this page:

• Run regedit (remember to run it as the administrator)
• Expand HKEY_LOCAL_MACHINE
• Expand SOFTWARE
• Expand Microsoft
• Expand Windows
• Expand CurrentVersion
• Expand App Paths
• At App Paths, add a new KEY called sqldeveloper.exe
• Expand sqldeveloper.exe
• Modify the (DEFAULT) value to the full pathway to the sqldeveloper executable (See example below step 11)
• Create a new STRING VALUE called PATH and set it value to the sqldeveloper pathway + \jdk\jre\bin
