Hi,
I am new to the Advanced Installer but was already succesfull in building an .exe package. Suddenly I received the error "File [C:\Program Files (x86)\Caphyon\Advanced Installer 18.8\stubs\x86\ExternalUI.exe] could not be read. Please check if the setup is not already running."
I am not aware of any changes I did in my project. Did reboot the PC serveral times, checked for processes in Task Manager, even reinstalled Advanced Installer 18.8 but nothing helped.
How can I handle this error?
