regedt32 caused program to no longer be able to be run

I have a program unable to register oleaut32.dll, resizer,dll, arwizard.dll so based on some research, I did what was recommended in regedt32, I started it, selected edit;permissions for the HKey_Class_Root, selected advanced button, made certain both checkboxes, inherit and replace were selected and clicked OK.  It said it was not able to change some permissions and stopped.  I did not save the registry prior to doing this.

I knew something was wrong with at the start/run command, it said it did not know what to do with cmd.  It said a problem with the file associations.  I could not then start any program from the start menu, click on properties for my computer.  I could login but then the icons did not show the proper pictures, just the default icon.  Nothing would run.

I tried to use the F8 key and selected use the last good configuration option but it did not change anything.

The only thing that really runs is Microsoft Outlook and Internet Explorer from the Start menu programs at the top of the screen.  Outlook does a reconfigure each time but does appear to work.

It looks like I would need to restore to a prior version of the registry or something to resolve this problem.

What do I need to do?

Then your best bet is to boot the system to safe mode and do a system restore from there as I mentioned above. If you can't boot to safe mode, then try safe mode with command prompt and execute the command I posted above.

Doing a system restore should replace the defective registry with a working copy.

How do you run it and how do you load it if I cannot get regedit to run.  I would expect that start/run regedit would not do anything.  Do I have to go safe mode or safe mode command prompt to get to a command prompt and run it.

I cannot get to the command prompt from within windows normal mode.

I would expect the command would be something like regedit fixncr.reg but what is the correct stepx.

Also, how do I run these programs if I cannot get to a command prompt, would it be done in safe mode, command prompt, but how do I get the file on the computer in the first place.

Normally .reg asociation is retained when everything else is lost, try simply double-clicking on it and see if the registry will import it. You can launch it from a downloaded copy on a USB stick or copy it to the affected machine, simply depends on how messed up things are(!)

Will windows explorer be able to copy files if this problem occurs.  How do I start windows explorer.  Clicking my computer does not do anything.

As a workaround see if you can get to regedit using the following:

Press CTRL-ALT-DEL and open Task Manager.  From there, click File, then hold down the CTRL key and click New Task (Run).  This should open a Command Prompt window. 

Enter REGEDIT.EXE and press Enter.

Just download the FixNCR.reg file to a usb memory stick and double-click on the file. It should run no problem.

I will see if it works.  I cannot at this point click my computer to bring up the windows explorer.  Maybe when I put in the memory stick it will open up windows explorer.  The problem I have is nothing opens at this point, not my computer, right clicking on my computer and selecting properties does not work.

Trying to restore basic file associations from safe mode command prompt said it could not restore all entries.  Some in use by system......etc.

Trying to do rstrui.exe said system restore is turned off (don't know if that is true or not) and said to turn back on in normal mode because it cannot be done in safe mode.  That appears to not be able to be done?

Unfortunately none of these solutions would work.  What happened is in trying to correct the permissions problems not allowing oleaut32.dll and others to properly register, it removed the permissions from the entire HKEY...ROOT.

I first added read/write permissions for everyone to this key.  All the missing (unreadable) key values now appeared and the system worked back properly.  I then restore SYSTEM, CREATOR OWNER, Admistrator group and User group permissions similar to other WinXP machines.  I then removed the everyone permission (R/W).

That resolved the all issue other than I still could not register oleaut32.dll and other similar dlls.  I used the Microsoft Fixit tool from the "unable to install windows XP SP3 access denied" knowledge base article and did a system scan tool check for proper system tools and this fixed the registration inability problem.
