No confusion...
As I wrote, I was able to Run the InstallManager under a different New User Account. As the folders were the Same , InstallManager Run and installed BiaB 2024 Till completion. So I can Use BiaB 2024 under my old User Account.
When i try to Run InstallManager under my old User i geht the Problem.
I will deinstall the InstallManager, deleted the Log Files and install again, Then i will send you the Log Files again.
Best
Walter
