So I managed to get around the problem by looking inside the EXE container. I saw there was an MSI file which was the application itself, and the others were the prerequisites: DirectX .NET, etc. By using `install_msi_if_needed`, I succeeded.
However, I'd like to know what was blocking the installation...
Hello , I want to create a package for a software publisher's program. I have no problem installing/uninstalling it using PyScripter. The thing is, during the installation, the installation progress window appears, but no interaction is requested.
