Hello,
We are creating a custom installer for our application, and so considered using the merge modules provided by NI.
All the dependencies are OK, and the .msi (which contains only the merge modules, since the global installer is created by NSIS) is created by WiX.
The error occurs at installation of the msi, the log file says :
(...)
NIMURegPartInfo: Starting action...
NIMURegPartInfo: About to get properties
UpgradeCodeError - (null) must have a value - exiting.
(...)
Looking at the msi file in Orca, I can see that the table "UpgradeCode" is empty, so I suppose that this why I get the error.
How do I fill this table?
Thanks a lot
