I have developed and executed a script successfully, and saved the same to QC. When I tried to execute the script from QC, the script is not executing. What are the possible reasons?

ANS:

1) Firstly, QuickTest Add-In for Quality Center has to be installed.
2) In the QTP Tools > Options >run tab you should have ‘Allow other Mercury products to run tests and components’ selected.
3) Make sure you are running QTP as an Admin
4) All the test resources have to be in the correct path
