Because that is a Windows system file. The Windows File Protection will automatically replace that file if you delete it.

Why are you trying to delete it anyway?

hongjun,

Is XP's system recovery disabled?  Most likely that is not disabled and is "restoring" the "lost" file when you reload.

Let me know if you have any questions or need more information.

What makes you think you have an old version?  Have you used XP's file system checker?  I would hesitate downloading and installing a system file that may not match your system.  System File Checker will look at your version of XP and look through the system files to find appropriate files.  You can run the file checker by typing "sfc /scannow" (no quotes) in the Run window (Start -> Run).

If system recovery has prevented you from deleting the file then it may also interfere with installing a different version.

before you delete you may try to unreg the library.

regsvr32 /u comcat.dll

Well to get the original comcat.dll just follow these steps (they are also commands).

1. regsvr32 comcat.dll /u

2. rename c:\windows\system32\comcat.dll comcat.dl_

3. expand comcat.dl_ c:\windows\system32\comcat.dll (located in your windows xp cd, under I386 named comcat.dl_)

4. regsvr32 comcat.dll

as bcohea stated above it is a protected system file, and will be restored to the proper version.

Also, try deleting the comcat.dll from c:\windows\system32\dllcache . Thats where it is restored from automatically...
