What is a software Installation?
It is a process where a new program is added to the Windows PC or any OS. During the process, new files are copied to the targeted location, DLLs and services are registered, and so on.

Lastly, every installer also comes with an uninstaller registered with the OS.

Why is my software not installing in Windows?
The primary reasons for the software not installing on your Windows PC include compatibility problems, architecture differences (32bit vs. 64-bit), insufficient permission to install software, corrupted system files or installer, etc. Apart from this, it could be specific to software as well. If these are not the problems, you can always connect with the developer to determine if additional or supporting apps need to be installed.
