Install Error 1603

[AutodeskCommunityUser]

Good afternoon, 

Last Friday my computer had a major failure. After it was fixed, we installed AutoCad Mechanical 2025. We ran into the Add-in programe we use currently does not work with 2025. We attempted to install 2024 but got an error during the install. "Install Failed - Error 1603. Fatal error during install". We uninstalled 2025 hoping we could then load 2024. It did not work. We uninstalled the Add-in. Rebooted the computer and tried again. Again, the same error pops up. We currently are stuck.

Any advice on how to fix this?

Thankyou for your helping. It had been decided that the install somehow was corrupt, or had been corrupted somehow. As this PC had just been fixed, new board and hard dive, It was easy to run it back to before the attempt. After doing that, AutoCAD 2024 loaded and is working well now. 

I appreciated the replies. Thank you very much.

Have a great day.

Non-Worked! Am I missing something it use to be so easy to download your software. It was just a push button, now you have to be a computer scientist. 😂

What did you try? What exactly did not work?

What is your exact error message?

What is your OS version?

Which software are you trying to install?

Something happened during the down load of 2025 that would not allow 2024 to also be downloaded. had decided to just go with 2025 until an add-on program wouldn't work with 2025. They said they are working on it. When I tried to go back to 2024 it would not install in. It kept crashing. As this PC was just repaired from that cloud strike thing, our IT decided to just start over. there wasn't anything to lose. That worked well. I am back on 2024 and will update to 2025 when the add-on program is also updated to 2025.

I appreciate the information. What it came down to for me was, I had to call Autodesk for assistance. I then Gave them access to my computer. They literally had to repair the core 🙄?
