Blair,
That is excellent information. Yes, I am on 3.5 currently. I'm no longer with Overwatch so I can make the call to go to 3.6 much easier. FWIW, in this install I have 1 immed. DTF CA that costs and then 2 more CA's that perform uninstall and install actions. The cost CA always works and then the uninstall CA fails about .5% of the time based on 800+ machines deployed so far. They are all Server 2008 R2 x64 SP1 Virtual Machines so maybe there's a problem there in CPU handling that exposes this race condition. Only problem at this point is since the work around to 1603 is to run the advertisement again I can't rebuilt the package to see if 3.6 fixes it or not. ---------------------------------------- From: "Blair" <os...@live.com> Sent: Wednesday, January 25, 2012 12:14 PM To: "General discussion for Windows Installer XML toolset." <wix-users@lists.sourceforge.net>, chr...@iswix.com Subject: RE: [WiX-users] Two Wierd Installer Problems - DTF and QuietExec Are these problems in 3.5 or 3.6? Last year I discovered a defect in DTF wherein a race condition upon completion of a DTF custom action call would cause a failure return to Windows Installer, even when the managed code custom action itself returned success. That was fixed in 3.6, but the bug remains in 3.5. The race condition is in the native wrapper code. It tends to manifest only when there is a heavy load (either CPU or disk) in the machine at the moment that the custom action is completing, and thus was very difficult to reproduce (I was fortunate enough to have exactly one box that reproduced it with any (but still uncertain) regularity, out of dozens of other boxes that would never reproduce it). You can take the SfxCA.dll files from recent builds of 3.6 and use them with 3.5's RTM build to get that race condition fix and an unrelated memory leak fix. I don't remember the bug numbers, but I do remember the investigation and fix of the race condition. I don't know what would cause the QuietExec issue, however. -Blair ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
