How to reinstall Windows Installer ?

[Lars]

When I try to, the system says the service already exists.

i tried to delete the :
msi.dll file (impossible --> in use...)
msihnd.dll
msiexec.exe

I then registerd these two dll files.

Still doesn't work...

Thanks by advance for any ideas.

Hi

Try the methods one by one outlined here to fix Windows Installer problems in
Win2k and NT4:

After running through the four points above, also try this from Start/Run:

msiexec /regserver


If that doesn't solve your problem, and you have MSI 2.0 installed, downgrade
to version 1.1 (somewhat messy), and then install MSI 2.0 again:

Ok, I found the solution.

These files are in fact protected files, and if are modified or
deleted, windows restores them.
Just needed to delete the restore sources, to avoid automatic restore
: dllcache folder an ServicePackFile folder.
