Hi Susan
Can you please define "crashes"? Error? Behavior? Etc.
What version of CR? Please be precise. E.g.; CR 12 is not precise (best place to look may be in the CR designer Help -> About.
See if a simple test .NET app that does not use interop and the UFL works. Could be as simple as;
CrystalReportsViewer1.ReportSource = "path to report"
Finally, note that CR 10 has been out of support for close to 10 years and upgrade to current version of CR and full CR SDK for .NET may be required.
BTW.; CR 10 did not support any of the current Operating Systems either. So WIN 7, WIN 2008, WIN 2012 would most certainly cause issues.
