VB.NET program requires administrator for Crystal Reports after install

I have a VB.NET app that utilizes Crystal Reports.

The program runs fine in Visual Studio and runs for me on any computer I have admin for. For users without admin rights, it crashes and says "Load report failed." immediately upon load.

I don't think it's the issue of it not being able to load a report, if I put a msgbox as first line in my code, it doesn't make it that far.

I have read and tried several fixes; most point seem to point toward the Windows temp folder or some other permission.

Could someone point me in the right direction? VS2019, Crystal 13.0.31.4010
