Hi, I was able to solve this problem and the earlier reported problem of custom action not running on XP. I am reporting this so others can benefit from it. The custom dialog used a background image which was in jpg format. Windows 7 could handle it. XP HOME SP3 also could handle it though it did not show the image, and reported error 2858. It did not abort the install. XP PRO SP2 simply failed. Thanks to all who suggested different possible reasons. Umesh
From: umesh_jogle...@hotmail.com To: wix-users@lists.sourceforge.net Subject: bitmap error 2858 Date: Wed, 18 Aug 2010 14:08:44 -0700 Hi, In our installer I am getting error 2858 when the installer is run on XP Pro 32. Actual log entry is Debug: Error 2858. The data for bitmap background is not valid. This problem is not seen on Windows 7. Has anyone noticed similar behavior? What could be causing this problem?
