Hi @Gurudas Anand Satardekar ,
Are you installing a new Exchange or a low version update?
By analyzing the error message and related searches, the error may have the following two reasons:

1. Check that the Exchange server meets the system requirements, the related error shows that there is not enough memory:

2. Check that the prerequisites are installed correctly:
