convert absolute path to relative path

You are providing TC, the exact location, using absolute path, to locate Vision.exe. If you were to use "relative path", how would you get to Vision.exe?

You can define an environment variable that stores the absolute path followed by the executable file. You should then be able to use, for example

%VisionPath%\Vision.exe

Where %VisionPath% could be either

D:\6.5\build\win64\vc15.0\Unicode Release
C:\Temp
X:\Something\Else

If your application doesn't depend on DLL's or it's own library files, then you can have Vision.exe within your TestComplete project folder. Try it, and see what happens.

The easiest solution is to use environment variables, which doesn't involve changing your TestComplete project, but that is entirely up to you.

As an example, have a look at https://stackoverflow.com/questions/1672281/how-to-set-the-environment-variables-for-java-in-windows. Regardless of what version of JDK you are using, to use the correct version you just adjust the environment variable JAVA_HOME.

The only solution I can think of, is using environment variable, as suggested.

There's no harm in trying what you suggested,

"i.e Instead of giving path as "C:\Testcomplete\v1.0\Testapps\vision.exe"
is it possible to give "..\Testapps\vision,exe"

assuming the test complete project file is in the path "C:\Testcomplete\v1.0\Project1"". 

hi, I have a question. Since I couldn't find where to ask a new question I am asking here.

In TestComplete keyword test I am facing an issue on opening the csv file from a path in the C folder. This was working very well earlier but now an error comes as below. Could you please help me with this. The csv file remains in the same folder itself and I haven't changed its path.

given below is the path to the csv file

earlier it was working well without errors as below
