32 bit programs don't work in Windows 7 64bit

post #1 of 8
Thread Starter 
Cousin's computer won't run ANY 32 bit program. I noticed this when CCleaner wouldn't run, but CCleaner64 did. Firefox and IE won't work but IE 64bit does.

I can't turn on any antivirus or security programs. MSI Afterburner and AIM don't work either. The other programs that do work are HWmonitor, word pad, mydefrag, and windows explorer and the two listed above. Computer is at stock and was previously overclocked.

Any fixes for this? System restore can't find the 3 restore points even though CCleaner 64bit found 3.

All I can say is, this does not sound right at all. Is this a relatively fresh install? Have you tried running Windows 7 SP1 to fix it (sometimes a SP can fix big issues)? Is there anything you've tried within MSCONFIG, permissions or REGEDIT?

Window 7 x64 has a compatibility program that is supposed to run most 32 bit programs.

I reinstalled Windows 7 for my cousin last Friday. Upgraded his heatsink and overclocked on Saturday. This morning all his 32bit programs stopped working after his computer froze and restarted itself.

I haven't touched MSconfig, permissions, or Regedit. Not sure what I can tamper with in thereto fix it.

Yup, maybe that program stopped working and that's why things aren't working?

System Restore worked through indirect control panel options, but nothing's changed.

I honestly would check for a virus, and if that isn't the case. I would go for a reinstall, sounds like something got seriously corrupt.

Check the shortcuts/app exe files of the 32bit apps are in compatibility mode (right click on a program go to properties selet compatibility then select run this program in compatibility mode)

Also, have a look at this --> http://www.sevenforums.com/tutorials/316-compatibility-mode.html as it might help.

Only 32-bit drivers won't work on 64-bit Windows. 64-bit Windows can run regular 32-bit programs for sure. Something is fishy.
