Hi, does anyone know why I am getting this error when trying to install an instance for the T290 course?



Installation runs and then it needs to apply a customization and then at this point it is failing

Here is the stack trace:

I have tried uninstalling and reinstalling with AcumaticaERPInstall.msi. I am downloading the 2025R2 Service pack 1 version. Have tried running installation with admin rights. After the error, the system is there, but I cant access it as its not properly installed yet. I am using MySQL as the database, but I have running versions of 2025R1/2025R2 on MySQL with no issues. AI says I am using the wrong version of Acumatica installation, but that’s not true? is it? Just following the instructions from Acumatica Open University. Any ideas?
