Hi; May I help.
You need to have installed the Timing Solution program per Kesk's post #1. You have copied into the folder the file TI.exe and use it to run the Timing Solution program. This file, TI.exe is the patch/loader.
To update per Kesk post above, just extract the contents of the of the posted .rar file into the Timing Solution program folder, ie C:\Timingsolution. Some files in the program will be overwritten. That's ok. The patch/loader TI.exe is still there in the program folder.
Now, as usual, to run the updated program, just run the patch/loader (TI.exe)
Hope that helps.
