using FUSLOGVW.EXE on a machine with no Visual Studio installed

As mentioned in an answer above and in comments, you need to do two things to get the fusion logger to run on a machine without Visual Studio:

1. Copy fuslogvw.exe to that machine. You can find it wherever you installed .NET (eg. C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\x64\FUSLOGVW.exe)
2. Copy flogvwrc.dll to the same location as fuslogvw.exe on that machine. You can find it in the 1033 subdirectory where fuslogvw.exe was (eg. C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\x64\1033\flogvwrc.dll)

Once you have fuslogvw.exe and flogvwrc.dll together in one directory, you can run the log viewer. You don’t need registry changes or any other changes.
