<div dir="ltr"><div>Hello, Alessandro and Qgis developer community.</div><div><br></div><div>Thank you for the feedback, Alessandro. I tried running a dependency walker on the program and, although it pointed out some possible error related to Qgis, I couldn't identify why this happened. As can be shown from the error lines below, the error appears to be related to the path to some python modules, however having checked, the paths appear correct. Do you have any insight into what could be causing this, and if this might be the reason for the error in launching the program?</div><div>The link below contains a zip file with the logs, one without Qgis installed, and one with Qgis. I appreciate the help. Thank you.</div><br><div>Possible Qgis related errors found in Dependency Walker:<br>LoadLibraryExW("c:\psr\hera\qgis\_gui.pyd", 0x0000000000000000, LOAD_WITH_ALTERED_SEARCH_PATH) returned NULL.

The problem is that Hera works on all computers that have Qgis installed, but only on some computers that don't have Qgist installed. While trying to install it in a computer that has never had Qgis installed, a critical error is given when we try to open the now installed program. The error message displayed is as follows: "Failed to execute script Hera" (as can be seen in the image, available in the link below). Every dependency that I could think of that could influence the installation was previously installed, such as all the possible Microsoft visual studio C++ packages, as listed below:</div><div>- Microsoft Visual C++ Redistributable for Visual Studio 2008, 2013, 2015, 2017 and 2019.</div><div>To test that the problem was truly due to the lack of some missing Qgis dependency, we created a machine on the AWS Amazon server and tried to install the software, as well as the
Microsoft visual studio C++ packages and the previously mentioned error was given. Only after installing Qgis on the machine was the Hera program successfully launched. However, after uninstalling Qgis on the same machine, the Hera program continued to run successfully, indicating to us that the source of the problem might be because of some dependency or configuration that Qgis does while installing. </div><div>Since PyQgis does not offer some kind of logging or error message showing the user whats could possibly be missing, I was wondering if anyone could offer me some insight into what it might be. I appreciate the help, thank you.</div><div><br></div><div>Link to the error message image:</div><div><a href="http://psr.me/1ayvzfn" target="_blank">http://psr.me/1ayvzfn</a><br></div><div><br></div>-- <br><div dir="ltr"><div dir="ltr"><div><div><span style="color:rgb(0,0,102)">Pedro R.
