Symptoms

Smart Forms upgrade setup thrown few warnings: "Installation in the global assembly cache failed: DataSourceCode.Data.Form_1_0_8.upgrade.sql"
 

Diagnoses

Warnings being thrown in the EventLogs after upgrading smartforms form 4.6.8 to 4.6.11.
Sample warning
Installation in the global assembly cache failed: DataSourceCode.Data.Form_1_0_8.upgrade.sql
 

Resolution

The installer logs don’t have any errors or warnings, and this is indication that the install was not compromised.
The Warning is thrown due to old legacy 4.6.9 msi that is still executed and some of these legacy files has the GAC flag enabled. It has no affect at runtime at all, it just tries to GAC and fails.

Future installers will exclude this msi’s.
