Use the original disk or download, and serial number if any. Some very old versions can no longer be installed.
You can download Acrobat from this website at adobe.com. Scroll down for the older versions. You must, of course, have your serial number to activate it.
Also, if you subsribe to Creative Cloud, you can reinstall it through the Creative Cloud app.
Is the serial number the same as the "Material No" on the invoice? I have the invoice that was used to buy the product. It is Invoice Number 876960994 dated Feb 13, 2018. Order Number is 5001400623, Customer No is 1452233. Please advise on how to re-install. File was corrupted on my system and I was advised to delete and reinstall.

No, the serial number is included in the packaging (if you get physical disks) or sent to you. You MUST keep a record, it really is what you pay for. However, if you register you can check you Adobe account for details.
If it is subscription things are different.
