MSJet40.DLL in use

[Guest]

I have just reloaded Win2kAS from scratch. I went to apply SP4 and got an error message: "Service Pack 4 Setup Error: The file [path to my install directory]\system32\dllcache\msjet40.dll is open or in use by another application.

I was able to apply SP2, but SP3 and SP4 continue to give me this error and there are no other appls running. The odd thing is, why would a running app be using a DLL from the dllcache? There is a copy of this DLL in system32 (dated 4 May 2001) and the one in the cache is 6 Dec 1999. Ideas?

Further info - I tried to rename or copy over or delete the DLL using Safe Mode, Recovery Console and O&O BlueCon and none of them were able to touch the file in any way. Sounds like it is just a really messed up file ... but I still cannot apply SP4!!!

Hi

I doubt that any processes is using files that are placed in the dllcache
folder, more likely it is caused by a permission/rights problem on the
file/folder...

The permission/rights on the file/folder can be corrupt, missing or revoked.
Verify that e.g. Administrator and SYSTEM have full control over the
file.

Several other people have had this problem for Win2k SP3 upgrades as well as
WinXP SP1 , on other files, with the same error message. After they fixed the
access rights, the service pack install succeeded:

In a command prompt (run e.g. cmd.exe from Start/Run to open one):

Run the following command:

cacls.exe %windir%\system32\dllcache\msjet40.dll


Here is the output from my Win2k Pro computer for a dll file in the
dllcache folder:

BUILTIN\Administrators:F
NT AUTHORITY\SYSTEM:F

If you get an error saying "Data error (cyclic redundancy check)",
the hard disk most likely has a fault (e.g. some bad sectors).
