FB 2.5 Windows installer doesn't detect existing FB 2.1 install
---------------------------------------------------------------
Key: CORE-4110
URL: http://tracker.firebirdsql.org/browse/CORE-4110
Project: Firebird Core
Issue Type: Bug
Components: Installation
Affects Versions: 2.5.2 Update 1
Environment: Windows 7, Windows XP
Reporter: michalk1
Priority: Minor
The FB 2.5 Windows installer doesn't detect existing FB 2.1 install and as a
result, overwrites it's service settings.
Steps to reproduce:
- Install Firebird 2.1.5, default settings
- Stop the Firebird service
- Install Firebird 2.5.2, default settings
Now, the only installed service is the FB 2.5 one.
The correct behaviour should be to show a warning message: "If you continue
with this installation Firebird will be installed but not configured".
The bug is probably in the following fragment of AnalysisAssessment function in
file FirebirdInstall_20.iss, which was left unmodified since FB 2.1 (another
resembling suspicious code is in SummarizeInstalledProducts function):
function AnalysisAssessment: boolean;
...
//If existing install of the same majorver.minorver is
//found then we can upgrade it.
if ( (ProductsInstalledCount = 1) AND
#if PlatformTarget == "x64"
((ProductsInstalled AND FB21_x64 ) = FB21_x64 ) ) then begin
#else
((ProductsInstalled AND FB21 ) = FB21 ) ) then begin
#endif
result := true;
exit;
end
;
...
