Hello
In our small team, we’re trying to install the latest version of Katalon Studio, specifically version 11.0.0. We’ve run it with elevated privileges, but it’s not working; this happens on different machines.

If it helps, here’s the installation log:

{“cause”:“Acceso denegado. (os error 5)”,“message”:“Extraction failed due to read/write permission! (“C:\Users\alopez\.katalon\packages\Katalon_Studio_Windows_64-11.0.0.zip”)”,“stack”:“Error: Acceso denegado.

Yes, the same issue was reported for the ver9 in Nov 2024. But I think it is not sad much. You have something you can try. Please find @bhavyansh.ameta suggested a solution in his post.

I found that @alopez.softland posted a similar issue at March 2025 as well. I think your machine environment has some condition that causes KS installer to fail. You should read the official doc again, and review your machine environment.

Hi @alopez.softland ,

Due to your error log (“os error 5: Access Denied” when extracting the package). It indicates that the installation folder is accessible (since the package can be downloaded successfully). But somehow it cannot extract the package. Maybe there is already a folder there from the previous installation, or a program is holding the extraction folder and preventing it from being removed…

So, my suggestion is to

  1. Remove the folder "%userprofile%/.katalon/packages" completely.
  2. Then close all the KS instances and the KS Installer instances.
  3. Maybe restart the machine too to ensure all the applications release their control from the KS installation folder.
  4. Just then retry to install again.

Additionally, you can download the KS package directly from these links and extract it manually if the installer has any issues:
