http://msmvps.com/blogs/michael/archive/2004/12/19/26352.aspxA while back, I posted a code sample on my blog that demonstrated how to implement MsiSetExternalUI in VB6. That post certainly got a lot of hits, but there was a catch that quickly came back to haunt me. The sample I provided worked like a champ in theenCommunityServer 2008.5 SP2 (Build: 40407.4157)http://msmvps.com/blogs/michael/archive/2004/12/19/26352.aspx#61086Wed, 03 Aug 2005 01:03:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:61086TrackBackImplementing a Windows Installer Validation Engine in VB6 - Part IIooeess<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=61086" width="1" height="1">http://msmvps.com/blogs/michael/archive/2004/12/19/26352.aspx#58714Fri, 22 Jul 2005 06:50:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:58714TrackBackImplementing a Windows Installer Validation Engine in VB6 - Part IIooeess<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=58714" width="1" height="1">http://msmvps.com/blogs/michael/archive/2004/12/19/26352.aspx#47837Thu, 19 May 2005 03:42:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:47837TrackBack^_~,pretty good!csharpsseeoo<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=47837" width="1" height="1">http://msmvps.com/blogs/michael/archive/2004/12/19/26352.aspx#42715Fri, 15 Apr 2005 22:29:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:42715TrackBack^_^,Pretty Good!<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=42715" width="1" height="1">http://msmvps.com/blogs/michael/archive/2004/12/19/26352.aspx#26436Mon, 20 Dec 2004 13:05:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:26436MichaelHello, <br> <br>I am working on the windows installer - particularly the validation part. <br> <br>I am facing a problem - when i came across your blog and thought of requesting help from an expert. Hope you won't mind my asking you here on the blog. <br> <br>the specific question is - if i install an msi and the try opening it again using MsiOpenPackage - should it work or not? If not why? If yes - why is it giving an error at my end? It fails giving ERROR_PRODUCT_VERSION. <br> <br> <br>Thanks <br>Bijoy. <br> <br> <br><div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=26436" width="1" height="1">
