Solved
The project suite or project you are opening in TestExecute is not a valid TestComplete project suit
I'm trying to generate the report using the below command, but unsuccessful all the time. What is the right way if someone can guide?
TestComplete.exe C:\code\Takeflight\TestProjectVinea\TestProject1.pjs /run /p:Calculator /ExportSummary:"C:\code\Takeflight\TestProjectVinea\TestProject1\output\report.xml"
Ok, I found the problem. It turned out to be admin permissions on the windows location, where TestComplete.exe file is located.
So work around I have to create a shortcut file for TestComplete.exe on desktop and execute via shortcut file.
.\TestComplete.lnk "C:\My Projects\MySuite.pjs" /some /other /switches
