I was using Professional Registry Doctor on my Win Vista PC when I received this invalid floating point error. 

Professional Registry Doctor

Invalid floating point operation.

I tried a reboot, but the same error message popped up. 

I tried to look for solutions in the Internet, but couldn’t find one. 

Any advice on how to fix the error?

Invalid Floating point error when using Professional Registry Doctor

I also once used a registry doctor, a different brand not the one you used, to optimize my registry and to help speed things up. It really fixed my registry especially the double entries in my startup.

It deleted all the blank entries that were mostly left by uninstalled applications. It also fixed some invalid entries that were created by some applications during their installation. You can even optimize the registry for a much faster accessibility. The registry tends to become a little loose because of the application’s installation and uninstallation.

If you are having that problem with your registry optimizer even if you already rebooted your computer, try checking your hard drive if there is any error. Use a disk utility application to check your disk or you can download Norton SystemWorks or Norton Utilities over the internet to help diagnose your hard drive. It diagnoses and fixes a hard drive for any possible errors in the file structures, misreported free space of the hard drive, cross-linked files, misallocated file space, invalid entries in the file system, and others. Or you can just use Windows disk check tool.

  1. Right click on drive C and then select Properties.
  2. Click Tools tab.
  3. Click Check Now.
  4. Check Automatically fix file system errors.
  5. Click Start.

Run the application again after the disk check. If the same error appeared, try restoring your computer to its previous state using System Restore. If still nothing happened, uninstall the application and then install it back afterwards. Always remember to use the registry doctor with caution. It can also ruin your computer’s configuration if you don’t use it properly. Always create a backup every time you fix the computer’s registry so you have a fallback if ever something goes wrong.

Here are the system specifications for Professional Registry Doctor:

  • Windows 98, Windows Millennium, Windows NT, Windows 2000, Windows Server 2003, Windows XP
  • Pentium 533 MHz or higher processor
  • 128 MB RAM
  • MME compatible sound card
  • 800 x 600 screen resolution 256 colors video card

This software only supports until Windows XP, and you are using Windows Vista.

It’s obvious that your operating system is not compatible with the application.

Just download the right version for your operating system.
