C.2 Error Levels

Like other applications installers made by NSIS return error levels as a result of their execution. Checking the error level can be useful if you call an NSIS installer from another application or installer.

Normal installers:

• 0 - Normal execution (no error)
• 1 - Installation aborted by user
• 2 - Installation aborted by script

Silent installers:

• 0 - Normal execution (no error)
• 1 - Installation aborted by user
• 1 - Installation aborted by script
