ive been wondering about it for weeks now and i finally stumbled upon something that solved it. i know there must be other people out there with this exact problem so i thought i'd make a topic that would be an all in one solution instead of having to scour google for 6 hours.

this is if you have already tried

start > run entering "regsvr32 VBScript.dll" and then pressing enter

and the dll still failed to register

along with blank search, windows media player not opening, crash upon javascript use in browser (IE?)

solution from:

FIRSTLY make sure you have Windows Script 5.6:

alternative link:

MOD EDIT: Backup your registry before making any changes to it. Without a backup, one tiny misstep can render your system unbootable.
1. open registry editor
2. use the down arrow to scroll though all entries in HKEY_CLASSES_ROOT
3. upon encountering an error dialog, right click on the entry giving the error and go to permissions
4. add user group "administrators" (use "check name")
5. tick all permissions boxes
6. click advanced and go to owner
7. click administrator group
8. tick box "replace owner on subcontainer and objects"
9. click apply and accept the error
10. cancel out of the box
11. click apply and then ok in the box
12. repeat for all offending entries
13. press F5 to refresh and perform the same step-by-step technique on the subfolders
14. take note of all fixed folders
15. if subfolders do not appear, try installing Windows Scrip 5.6 again and THEN searching for the subfolders

dont ask me why, but i couldnt apply the new administrators permissions without first opening the "advanced" dialog and triggering the error there. if someone can make adjustments to this fairly sketchy method, please feel free.

This appears to be a workaround to something that's trashed the registry permissions for these objects. I'd use the RRT from here: http://www.sergiwa.com/en/rd/download.html or the Repair Permissions tool in Dial-A-Fix myself.

Should you choose to use these instructions, be sure to backup your registry first!
