I know that in Delphi 5 it is impossible to write Int64 to Variant and OLEVariant and so, to use it in Type Library (TLB) file of COM Server.
Does anybody know or had experience with Delphi 7 regarding of usage int64 values in COM Server interfaces?

No restriction on Int64 in Delphi 7 variants: it is supported, in the standard way:
There is indeed the OLE/COM compatible type definition
varInt64 = $0014; { vt_i8 20 }
in the System.pas unit, and all needed conversion in the Variants.pas unit.
I confirm it was not supported in Delphi 5.
