I have a problem trying to install anything.  I always get this window:

Windows Installer
the feature you are tryingto use is on a network resource that is unavailable.  Click OK or enter an alternate path to a folder containing the installation package W[11SP1DWPPP.msp in the box below.
User source: C:\DOCUME~1\VORAL123\LOCALS~1\Temp\{54F90B55-BEB3-4F0D-8802-228822FA5921}_7582\

Another window says, "This installation source for this sproduct is not available.  Verify that the source exists and that you can access it."

I have been trying a varity of things and got an error 1211 message one time.  Does anyone recognize this problem?

I reloaded Installshield.  I want to try reloading Windows Installer but not the whole OS.  Is there a way to reload just Windows Installer?

Also I am getting suspicious I caught a virus.

Yest it is the same problem and worse than I thought.  

Right after I entered my quiery it occured to me to try a search for fix installer xp.  I found Windows Installer 3.1. So I tried that with still no
success I had a false feeling of success when the program asked to update a file and installed successfuly.  But I had the same problem when I tried to install a game.    

The virus scan TrendMicro did not turn up any viruses or worms.

I did further looking around and found that the number that is supposed to be in the temp file, which is empty, is located in Local Settings. {54F90B55-BEB3-4F0D-8802-228822FA5921}_7582\.  That number is the same number in the game disc file: Type Configuration Settings\Product Code but without _7582\

Is there some way I can find out more about how Windows Installer is supposed to work to find out why mine doesn't?

My word processor is operating faulty.  My disc drive does not reconnize a new disc until I restart the PC.  Also, the Recycle Bin was not eliminating deleted files.  They are turned into unknown or hidden files and supposed to be eliminated  after a certain build up.  I found the cure where someone had the same problem in a form and someone else had the solution (Replace a missing instruction in a file.)   With several problems occuring like that, I suspect something in common with them.
I must have cause some cruption in my hard disk.

I would like to report my success on correcting a problem I had with installing programs and getting this error message:

The feature you are trying to use is on a network resource that is unavailable.
Click OK to try again, or enter an alternate path to a folder containing the installation paccage.
'WP11SP1DWPPP.msp' in the box below.
C:\DOCUME~1\VORAL123\LOCALS~1\Temp\{54F90B55-BEB3-4F0D-8802-228822FA5921}_7582\

I went on a solid three day bing pursuing any leads I could think of. I went hither and yan. I'll spare the details only to say it was a odyssey on the internet.  Many false leads while learning about what is out there. I even did a repair install and all that involves.  

Just this morning of the 4th day I got up and decided to take a fresh look at the problem.  I then did what I could have done in the first place.  I did a search for network+resource windows+installer.  The led to a software maker that had the same problem that gave advice to its customers.  It refered to an  article from support.microsoft.com giving the solution.  

It turned out I most likely deleted an installation registry file by using a register cleaner.  I have several and I don't know which did it.  It was not till much later that I recognized the problem and too late to try restoring the backup register files.  The article I found described a program titled Q238413 Windows Installer CleanUp Utility at http://support.microsoft.com/default.aspx?scid=kb;en-us;290301.

It's a good thing I am retired and live alone.  I could devote a full three days to hunting down a simple solution to an agravating problem.  But I feel for those who have to work for a living and have little time for such things.  Getting technical help is dubious at best and can be costly.  

Well now I feel better and can take a break and return to a better runing system to catch up on my things of interest.
