I uninstalled my wireless adapter due to a very minor problem (which I wish I had ignored).  Now when I try to reinstall I get a "Data is Invalid" error.  Also, the program claims it cannot see the hardware, but Windows definitely does see it.

 

I also noticed that my Device Manager now comes up blank.  It show absolutely no devices.

 

Please help.  I am using Windows Vista (32 bit).

You should run a SFC /scannow in windows command prompt. Make sure you run it as administrator.

Thank you for your reply.  I did run SFC.  It did not solve the problem.

 

I did notice in the CBS file (that resulted from the SFC) that there are entries from the day when I trying to do the uninstall and trying to fix this problem.

 

The CBS file is much too big to upload or copy here.  I have attached just the entries from July of 2015 (which might be the only relevant entries).

 

I hope that the solution is hidden somewhere in here and that someone can interpret this and help me with it.

 

Thank you.

Hello, sir GardenGuy2 :)

 

Have you also tried to run your operating system on Safe Mode and see if the Device Manager is blank there, as well?

Thank you for the question.  Device Manager is also blank in Safe Mode.

Here is one potential thing to try. I have seen this on a few forums across the internet. 

If the Device Manager is till showing empty list try the following -

  1. Click Start, click Run, type services.msc, and then click OK.
  2. Double-click Plug and Play. (If you receive a Configuration Manager message, click OK.)
  3. In the Startup Type list, click Automatic, and then click OK.
  4. Close Services.
  5. Restart the computer.

 

If this doesn't work I noticed most people had to edit the registry.

Thank you for the suggestions.  Plug and Play settings cannot be changed (at least in the current state of the computer they are greyed out).  I have tried editing the registry as I've seen with other suggestions online.  When I do this, I get to a window where I am changing permissions.  I can make changes here, but the computer will not keep the changes.  (I don't have this in front of me right now, but when I click on Apply or OK the computer says something like it can't keep the changes.)

It turns out that the solution was System Restore.  System Restore did not work when run from within Windows, but when I tried running it by choosing "Repair Your Computer" (F8 at startup, etc), this time it worked.  Honestly, it's possible that it just worked because I used a different restore point, but I don't think so because I had already tried at least 3 other restore points when I ran this from within Windows.

 

Thanks again for all of the suggestions.  I hope my solution will end up helping others also.

If you have too many problems you can always wipe and reload the machine. I like to do it once a year just to keep my machine running at it's prime.  Sometimes things just need to be wiped haha.  System restore is similar, and I am glad it is working for you. I wish I could have helped you more!

Was just about to suggest Sys Restore until & scrolled down enough to see you did it.  Reckoned that would resolve.
