Hi @michiel, thank you for helping me.
I have tried to run the support tool located at c:/xampp/bnsupport/bnsupport-0.7.14-windows.exe but it exits with an error "Error writing file C:/Users/Dev/Desktop/bnsupport-7f14b05c5de2e186/bitnami-magento-info-20190930-115141-4076/permissions/letsencrypt.permissions The application will exit now." This has happened even when running it with administrator privileges.
I'm not sure changing the folder names in the configuration will help because even if I change the folder name back to the original c:/xampp the server will not start. I think the issue may be linked to the windows service that is created when the bitnami xampp installer first runs?
