Solved 32 bit program on 64 bit OS

January 1, 2013 at 01:58:56
Specs: Windows 7 Home
Had to restart laptop b/c web browser froze. A DOS screen popped up with a recommendation to run CHKDSK - so I did. Now, at start up, I first get the Windows Resuming window, then the error: "Unsupported 16-bit Application: The program ....C\Windows\system32\LogonUI.exe cannot start or run due to incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available." I can't get past this message. Tried Boot Options but only got system setup. Tried Windows 7 reinstall but the disk won't read and I get the same error. Can anyone help???

It sounds like you have an infection, possible that chkdsk window was a fake and you inadvertently installed something. Start and try hitting F8 and boot into Safe Mode. If you get into Safe Mode, run System Restore to a date WELL before the problem first began. After the System Restore completes, restart into Safe Mode with Networking and install, update, and run Malwarebytes to clean out all remains. Remove all it finds. Then update and run your antivirus program and remove anything it finds. Restart normal and see how things work.
If you cannot get into Safe Mode or cannot run System Restore, you can use a Windows 7 Repair Disk and boot to that (you may need to 'hit any key' to boot to CD/DVD or possibly reset BIOS to be able to boot to yout optical drive). From the Repair Disk, you can run System Restore (uses restore points on your hard drive) as well as a Start Up Repair and even reload any disk image you may have made from Windows Back up. This is a really good tool to have and you should have mode it already from the Back Up section. If you did not make one yet, you can still make one from any other working 64bit Windows 7 machine (or 32bit if it was a 32bit installation) and use that.

You have to be a little bit crazy to keep you from going insane.

The message is self explanatory. Some or all of the offending program is 16 bit code which is not compatible with your OS.

You may be able to run the program in a Windows compatibility mode.

What web browser are you trying to run?

I can't get to any screen to run in compatibility mode. I was running Firefox but had the same problem with IE. The program I'm trying to run is presumably Windows. I realize the message explains it all but I don't know how to get past it. I can't "resume " anything.

Are you able to boot into Windows? I find it hard to believe that LogonUI.exe would simply fail to work all of a sudden

Nope, can't boot into Windows. I'm finding it hard to believe as well and really wonder what the heck really happened. I haven't had the CHKDSK window with this computer before so that was my first surprise. After that - nothing.

I've been using this laptop without problems for over 2 years. Always booted up just fine.

LogonUI.exe is definitely 64-bit. If Windows claims it's 16-bit, then it had problems with LogonUI's now corrupt header. If you have a Win7 64-bit DVD, boot from that and run Startup Repair. If your system recovers, back up everything you care about, because you're going to loose it very soon.
