Windows Vista Registry Error

Every time that I intall or uninstall an application, after reboot...  The Registry Tools that I use are;

1. PC Tools Registry Mechanic, which automatically scans for Errors
2. Uniblue REGISTRY BOOSTER, which also automacally scans for Errors

Don't use BOTH (Registry Mechanic, REGISTRY BOOSTER) during the SAME BOOT, reboot after every scan.

Keeps my computer really fast.

Thanks.  But I prefer not to use any tools to fix the issue.  I would like to know what is causing the problem and what registry key I need to modify to fix this issue.

Using the tool will tend to fix or create other issues.

Look under here for an invalid network location.....

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
and
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

Also, do the same under HKLM. And make sure any empty values are populated, with a reachable location on the drive.....

what exactly am i looking for under these keys.  i am baffled and i have tried every forums i have visited.  i made sure both HKCU and HKLM has values.  

Personal for example....

Should point to your My Documents folder.....
Favorites, same thing to your Favs folder....

Can you export the 4 keys, both under HKCU and HKLM and post here please?

They are all pointing to the locations as specified. I don't see anything unusual.

No network locations specified? Thats usually where I have seen this error.... Odd....

One other thing....

Search this key for the network location it is specifying..... "/0"

ok.  so you want me to seach for "/0"?

yes....

in which Key?

Last one.... Or whole reg for that matter....

ok.  i will work on it tomorrow.  thanks

@Kaushalk

i"ll suggest you to issue sfc /scannow command in cmd (Vista DVD shold be inside yours DVD drive already before pressing enter)

this command usually solve these weired problems.

or at last resort you can do system restore like this hopefully it will work

i have tried both options.  both failed.  it is really something in the registry that i need help on.  lol.  i need a registry expert.  

john.....i will get back to you, once i work on your suggestion.

John,

I searched the whole registry for "/0" and found nothing except for dates.....

any other suggestions...

A Screnshot would be helpful.....

Is there a log provided by this installer?

All application installs, or just one?

Process Monitor
http://www.microsoft.com/technet/sysinternals/utilities/processmonitor.mspx

Set the filter at the top to Include "Result" is "NOT FOUND" then "Include", and then try and recreate the errors by trying another install. Look at the logs, and see if you can see what it is trying to find......

i have attached HKCU, usershellfolder
HKCU-UserShell.txt

John,

Do you need other Keys as well?

The regular Shell Folders please....

It might be choking on these 0 data values. Empty values will cause this as well........ Change them to the proper folders, either under "D:\Anu\Documents", or %userprofile%\My Pictures ( and My Music, and My Video accordingly...)

Value 18
  Name:            My Pictures
  Type:            REG_SZ
  Data:            0

Value 19
  Name:            My Music
  Type:            REG_SZ
  Data:            0

Value 20
  Name:            My Video
  Type:            REG_SZ
  Data:            0

HKCU - Shell Folder
HKCU-Shell.txt

Retry....   :)

BINGO !!!!!.  That fixed my problem.  Thanks John.  Thanks a bunch.

Excellent Solution.

SWEEEEET!!!!!!!!!!!

Glad we finally got it.....
