Alex,    Thank you!  I see that FileSearch has a similar functionality to what I need. -- Dustin Johnson CACE Technologies Tel: 530-758-2790 x109 Fax: 530-758-2781 www.cacetech.com Alexander Shevchuk wrote: Hi Dustin,   In case you need to check if third party software is installed on the target system, use: AppSearch (http://msdn2.microsoft.com/en-us/library/aa367578(VS.85).aspx) and LaunchConditions (http://msdn2.microsoft.com/en-us/library/aa369751(VS.85).aspx) actions.   In WiX the equivalents are <Condition>, <AppSearch>, <DirectorySearch>, <FileSearch>, <ComponentSearch>, and <RegistrySearch> elements. Generally, you set the property value depending on the result of the <…Search> and then check the property value in the <Condition>. You  want to schedule <AppSearch> action before <LaunchConditions> if you want to cancel an installation in case required third party software is not installed.   Alex       From: Dustin Johnson [mailto:[EMAIL PROTECTED]] Sent: Friday, February 01, 2008 10:02 AM To: Alexander Shevchuk Subject: Re: [WiX-users] Checking for executable version number   Alex,     Thank you for your response!  I am familiar with these methods (though I have yet to try them).  Am I wrong in thinking that this only applies to files that I control and are in my installer?  My quandary here is that I depend quite a lot on outside applications being present and at least a certain version.  These applications are not mine, nor have they been installed through a previous msi.  The files are simply there and I need to check their version.  Is this possible? -- Dustin Johnson CACE Technologies Tel: 530-758-2790 x109 Fax: 530-758-2781 www.cacetech.com Alexander Shevchuk wrote: Hi Dustin,   MSI will do it for you.  Read about Patching and Upgrades: http://msdn2.microsoft.com/en-us/library/aa370579(VS.85).aspx and read tutorial on this topic: http://www.tramontana.co.hu/wix/lesson4.php File versioning rules: http://msdn2.microsoft.com/en-us/library/aa368599(VS.85).aspx   Regards, Alex     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Dustin Johnson Sent: Friday, February 01, 2008 9:48 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Checking for executable version number   Hi all, I'm pretty new to Wix and microsoft installer in general.  I have read everything I can get my hands on, but I still don't understand if I'll be able to retrieve the version of an existing dll or other executable and decide if I need to replace it.  I understand that I can write my own custom action, but this seems to be pretty basic and hope that someone has already done it.
