Guest martin0820 Posted July 25, 2007 Posted July 25, 2007 16-bit applications no longer run on my PC. This includes a part of Adobe Lightroom (!) that checks periodically for photos to download (apdproxy.exe). If it is attempted to run a 16-bit application, Windows reports the error: "NTVDM has encountered a problem and needs to close." Until recently, 16-bit applications ran OK. I'm not sure what caused this problem; it may have been installiing Adobe Photoshop Album Starter Edition, or it may be that this application uncovered the problem. I obtained hotfix 890076 from Microsoft and installed it with no errors reported. Per the associated knowledge base article, the files listed below are supposed to update, however, only Ntvdim.exe was updated; the rest retained their original timestamps. (Yes, I applied the registry change.) 06-Jul-2005 22:59 3.10.0.103 92,224 Krnl386.exe 06-Jul-2005 22:56 33,840 Ntio.sys 06-Jul-2005 22:56 34,560 Ntio404.sys 06-Jul-2005 22:56 35,648 Ntio411.sys 06-Jul-2005 22:56 35,424 Ntio412.sys 06-Jul-2005 22:56 34,560 Ntio804.sys 06-Jul-2005 23:49 5.1.2600.1715 397,312 Ntvdm.exe 04-Jun-2004 00:43 5.1.2600.1562 245,760 Wow32.dll 06-Jul-2005 23:38 5.1.2600.2715 420,864 Ntvdm.exe 06-Jul-2005 23:41 5.1.2600.2715 30,720 Arpidfix.exe I'm not sure what to do next. Is this due to one of the files listed above, something added to the registry... ?? Can I copy files from a PC known to be OK, and if so, which ones? The PC in question is an Asus P4P800E mb with Radeon 9600 video with XP Professional SP2. SP2 was installed recently, but this problem predates the SP2 installation.
