something you get or load a tool and it won’t start due to a missing Runtime or dll.
Such issues can solved with sxstrace tool. An example:
I want to run the makeappx tool from the Windows SDK on another host. The application won’t start:
D:\> makeappx.exe The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail. "D:\temp\makeappx.exe"
Start logging and open another shell and execute the command again
D:\> sxstrace.exe Trace -logfile:D:\temp\sxs.etl Tracing started. Trace will be saved to file D:\temp\sxs.etl. Press Enter to stop tracing...
Press enter in the sxstrace windows to stop logging, convert the etl file into a text file and open it with your favourite texteditor.
D:\> sxstrace.exe Parse -logfile:D:\temp\sxs.etl -outfile:D:\temp\SxsTrace.txt D:\> notepad D:\temp\SxsTrace.txt
In the file you should found some hints what is missing:
