Opening a project is very slow


While back I installed the Enterprise version of Katalon studio. After 90 days of trial, I uninstalled the enterprise version and installed the standard version. (Since there was no uninstall feature I had just deleted the folders from my users folder and any other place I could find Katalon.)

Problem is now it takes about 17 minutes to launch the project. Why is it so slow?
I try to use “Clean Project” at least once a day, but that doesn’t help at help.


You mostly wasted your time, after the trial period (which I think is 30 days) KSE becomes KS. And fyi, there is little functional difference between the two, from a testing perspective.

  1. Close Katalon.
  2. Go to your project folder and delete these highlighted files and folders


  1. Restart Katalon.

Hopefully, that will get you running.
