Hello DEADLIEST_GHOST,
I understand that you are receiving the error “The application was unable to start correctly (0xc0000005)” when trying to download or launch Roblox on your PC, and I can see how inconvenient this is.
Based on the official Roblox system requirements, Roblox currently installs on 64-bit Windows 10 or Windows 11, and Windows 7 is not listed as a supported operating system for the Roblox PC application.
For your reference, I’m sharing the Roblox support page below. Please note that this is a third-party website and is not owned, maintained, or managed by Microsoft. Because of that, Microsoft cannot control the content, availability, or any changes made on that site: https://en.help.roblox.com/hc/en-us/articles/203312800-Computer-Hardware-Operating-System-Requireme…
If you would like to continue using Roblox on this device, the available direction would be to use a supported Windows version, such as Windows 10 64-bit or Windows 11 64-bit, provided that the PC hardware also meets the requirements. Roblox also requires higher feature level support and recommends at least 1 GB of memory and 300 MB of free storage space.
I hope this helps point you in the right direction. Thank you so much for your understanding.
