Could you specify whether If you have unlocked any McAfee Anti-Theft Vault, and then shared it on a network; if so you cannot lock that Vault again until sharing is disabled.
Even empty vaults will not relock on command in my 64-bit WIN 7.
On my XP system - no problem.
If the McAfee Anti-Theft registry key is damaged or missing you will be unable to lock Vaults. To verify that you have this issue, perform the steps below.
Click Start, Search, and type regedit.
In the Search Results, right-click Regedit and choose Run as Administrator.
Navigate to the following registry key:
Verify the following information by double-clicking the keys listed below:
Error Control has a value of 1
Start has a value of 0
Type has a value of 1
If any of these values are incorrect, close the registry editor and continue to the solution steps below.
Run mcafee virtual technician from http://mvt.mcafee.com
Restart the computer after MVT completes and check whether you are able to lock the vaults. KIndly report back if you have any issues.
registry values are correct.
MVT found registry OK and failed to resolve problem.
I keep thinking this app might not be compliant w. 64-bit WIN 7???
If you still cannot open McAfee Anti-Theft after running MVT, you will need to reinstall the program.
Note: Personal Vaults, and the data stored within them, will not be lost if you reinstall McAfee Anti-Theft. All Vaults will be available after a successful reinstall.
Of course - I have reinstalled the app a number of times - no help.
The McAfee techs did also while controlling my computer.
I downloaded and reinstalled the current version from McAfee.
Vaults will not relock on command - even when empty.
Sorry for the inconvenience caused , This seems to be unusual .
I shall make a research on the same and shall keep you posted on the same.
I have followed this thread as I have the identical problem described by jstearns. I have a 32 bit Windows 7 installation in which the vault will not lock after creation even when empty. The "file open" error message is the same as described by jstearns. As a test, I installed MAT on a Windows XP laptop where it works fine
I use the same current version on WIN XP machines and it works fine.
On, at least the 64-bit, WINDOWS 7 it fails to relock on command with the same message that there are open files even when there are NO files in the vault - empty vault.
The McAfee web site says this is WIN 7 compatible. This has got to be a growing problem as more people switch over to 64-bit WIN 7 and get a bad feeling about McAfee because of the frustration over buggy software.
