Kathryn its possible I'd test it if I could, we don't have many fixed assets clients with 100 standard to be able to test it. For premium/advanced sage the following are the exact steps we do to get it to work, but no promises. I expect this would be applicable with other sage products that also use crystal 2016. Someone more gifted than I could probably explain why these help, or trim down the steps.
1) uninstall any old sage or any version crystal not 2016
2) install crystal 2016
3) install fixed assets 8.1
4) uninstall Sage erp
5) install sage erp
6) **place the pvxwin32.exe.config, one from a currently working sage 2018 erp attached, in the home folder of the sage server and (after launching it once) the workstation (this is the same as the fix for when you first install sage 2018 for crystal)
7) repair sage fixed assets
*on Terminal Server it did require us to log off and back on.
**in tests this did not break the non fixed assets workstations at all.
