>From Windows 2000 onwards, MDAC is part of the operating system, under Windows File Protection, and can only be upgraded using an OS update/hotfix-style package or by a service pack. The only supported method of installation is to run MDAC_TYP.EXE.
There is no newer version of MDAC for Windows Vista. Any merge module you find is likely to either simply have detection for MDAC, contain custom actions to launch MDAC_TYP.EXE (BAD! - example at http://support.microsoft.com/kb/320788), be an unauthorized repackaging which is unlikely to work, or be an out-of-date version. I'd strongly recommend launching MDAC_TYP.EXE from a bootstrapper application. -- Mike Dimmick -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Arnson Sent: 26 April 2007 15:59 To: Gareth at Serif Cc: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] UAC Prompt Required Gareth at Serif wrote: > MSI_LUA: Credential prompt is not required at this point, product is managed > and deployment compliant > Specifed source is already in a list. > Take a look at http://blogs.msdn.com/rflaming/archive/2006/10/01/uac-in-msi-notes-is-this-i ntentional-if-so-why.aspx: Maintenance mode operations such as repair or feature state changes do not require credential prompts. So that's working as designed. The question is why do the MDAC merge modules require elevation. Do you have them in a single feature? You should be able to then use VersionNT to disable the feature on Vista. -- sig://boB http://bobs.org ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
