This article shows what to do when the TAP adapter is not installed on Windows 7 computers when running the Ecatcher 7.0.3 (or >) setup.
Reminder : Windows 7 is officially no longer supported by Microsoft and therefore by Ecatcher as well.
Talk2m: Ecatcher
My Ecatcher TAP adapter is not installed on the Windows 7 PC.
Most likely the computer running Windows 7 does not allow or support the powershell scripts used by the Ecatcher setup.
A work-around can be to use the previous BAT and VBS files used in the older version of the Ecatcher setup (See attached).
To install it simply run the "install.bat" file and then the "rename.vbs" file in the cmd prompt with Administrator rights.
