JScript class has been modified to point to a different dll as seen via the registry:
HKCR\JScript\CLSID\(Default)
Data: {f414c260-6ac0-11cf-b6d1-00aa00bbbb58}

HKEY_CLASSES_ROOT\CLSID\{f414c260-6ac0-11cf-b6d1-00aa00bbbb58}\InprocServer32\(Default)
Data: <path to third party dll>

Note: Additional classes may be similarly modified, such as VBScript:
HKCR\VBScript\CLSID\(Default)
Data: {B54F3741-5B07-11cf-A4B0-00AA004A55E8}

HKCR\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}\InprocServer32\(Default)
Data: <path to third party dll>

1. Open a cmd.exe prompt as administrator.
2. Run: regsvr32 C:\Windows\System32\jscript.dll
3. Confirm in the registry that the correct DLL path is now present.
4. Repeat steps 2 and 3 for vbscript.dll, if necessary.

Expected values:
HKEY_CLASSES_ROOT\CLSID\{f414c260-6ac0-11cf-b6d1-00aa00bbbb58}\InprocServer32\(Default)
Data: C:\Windows\System32\jscript.dll

HKEY_CLASSES_ROOT\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32\(Default)
Data: C:\Windows\System32\vbscript.dll
