--- Comment #3 from Ben bvandermerwe@kbcat.com --- I have attached the log when it fails. Of interest, and I am guessing, please note: Line 10: It parses the manifest file in the exe Line 18: It notices kcunitop.dll in there.
If you search for the GUID C4203DFD, around line 40285 for example, you will see that it decides that nothing is registered.
Note that the exe manifest contains the registration COM free line for the COM component, but it is being cocreated in another dll which is automatically loaded when the exe is loaded. I don't know if that is maybe the issue under wine?
Maybe line 18 should contain more information about the item?
