MSI packages use special characters to indicate DWORD or binary values. In you Launch Condition, set MSMQEXISTS equal to #1 rather than 1 and it should work just fine. For more information about registry searches, check out: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/r eglocator_table.asp The bottom of the page shows how to search for values of differing data types. -- This posting is provided "AS IS" with no warranties, and confers no rights.

I'm trying to see if MSMQ is installed, and if its not, abort the installation. The registery search is setup as follows: (Name) MSMQ Property MSMQEXISTS RegKey Software\Microsoft\MSMQ\Setup\msmq_Core Root vsdrrHKLM Value (left blank) Launch condition set as: (Name) MSMessageQueue Condition MSMQEXISTS=1 Message [MSMQEXISTS] my error message I've tried different Values for the Registery search, as well as changing the condition for the LC, but nothing seems to work (except setting Condition to 1=1). What am I doing wrong? Thanks Andy |

I changed the registry value of Software\Microsoft\MSMQ\Setup\msmq_Core to 0, and the LC doesn't abort the installation. Basically it seems to always evaluate to true. Even if i delete the msmq_Core value completely, the installation doesn't stop with the error message that MSMQ is missing. Any other ideas?
