[wix-users] Unable to harvest reg entries from 64bit .Net DLL

I'm experiencing the following error when attempting to harvest
registry entries from a 64bit .Net DLL (assembly):

heat.exe(0,0): warning HEAT5150: Could not harvest data from a file
that was expected to be a SelfReg DLL: filename.dll.
If this file does not support SelfReg you can ignore this warning.
Otherwise, this error detail may be helpful to diagnose
the failure: Unable to load file: filename.dll, error: 193

Harvesting registry entries from the same DLL works nicely in 32bit,
so the problem appears to be 64bit-related.

I’ve just opened https://github.com/wixtoolset/issues/issues/6244 in
this issue, but thought it could be useful to also seek assistance
through the mailing list.

Best regards.
