All four downloadable program files are self-extracting executables which, when double-clicked, create new files and folders on your hard drive. Two of those four programs require no further installation, but the other two create an additional Setup.exe file which must be executed to complete the installation.
Turn ON the PC and start Windows. Create a new folder on your hard disk with a name of your choice, and download the free software into the folder. Double-click the file necessary for your WT series model, then click OK in the dialog box. A new folder, YOKOGAWA, will be created on drive C and files will be extracted to it. Specify any changes you wish to make to the destination folder.

When the extraction is finished, check to see if the program executable file was created (C:\YOKOGAWA\WTx000harm20e2.exe or C:\YOKOGAWA\WT2000flick\flick.exe). If so, installation is complete. If the Setup.exe file (rather than executable files) was created you will need to perform a few more steps to complete the installation. Double-click the Setup.exe file, and follow the on-screen instructions.
