Hi WiX gurus, I'm using the "supposed" standard way of detecting multiple SQLServer instances...
<Property Id="SQLSERVER"> <RegistrySearch Id="SQLServer" Root="HKLM" Key="SOFTWARE\Microsoft\Microsoft SQL Server" Type="raw" Name="InstalledInstances"/> </Property> <Condition Message="This application requires Microsoft SQL Server. Please install Microsoft SQL Server then run this installer again."> <![CDATA[Installed OR (SQLSERVER><MSSQLSERVER)]]> </Condition> But the Condition... <![CDATA[Installed OR (SQLSERVER><MSSQLSERVER)]]> Does not evaluate correctly. For instance if the Property SQLSERVER only contains "[~]SQLEXPRESS[~]" ( according to the log ) It still allows the installation to proceed when it should not, so I'm not convinced that using the >< is the correct way to check if 1 value exists within a REG_MULTI_SZ variable. Can anyone enlighten me as to what I may be doing wrong. Also where can I find the correct documentation/list to find out what are the correct conditional operatives I can use within a Condition statement in WiX, preferably with examples. I Googled various sites, but nothing definitive or helpful. Thanks. Dominique.
