[wix-users] Issues with Harvesting COM and GAC DLLs

[Ven H]

I am trying to harvest some dlls which have to be eventually deployed to
GAC through installer. When I am calling the heat command as below, I am
getting some
errors / warnings as mentioned below.

*heat.exe dir "D:\\InstallTest" -cg \"MyCompGgroup\" -dr MY_DIR -gg -g1
-srd -sfrag -var var.OutDir -out "D:\\InstallTest\\MyComps.wxs"*

1. *Could not harvest data from a file that was expected to be a SelfReg
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 the file.*

2. *Could not harvest data from a file that was expected to be an assembly.
If this file is not an assembly, you can ignore this warning. Otherwise,
this error detail may be helpful to diagnose the failure. Could not load
the file or assembly 'Assembly Name' or one of its dependencies. The system
cannot find the file specified.*

Actually, the files which are being mentioned as missing, are actually
present in the same directory.

I am also trying to harvest some COM components with the same heat command
as above. I am getting the below warning

*Ignoring the Registry key 'Interface\{Guid}\Something', it has already
been added to the Component 'cmpGuid'. The registry value '{Guid}' will not
be harvested.*

For one of the COM components, the heat command even fails with the
following error.

*heat.exe : error HEAT0001 : '.', hexadecimal value 0x00, is an invalid
character.*

Exception Type: System.ArgumentException
