Software Deployment

The MSI is attempting to overwrite a system DLL which is protected by Windows File Protection. You can generally ignore the error, but I would suggest removing the DLL from the MSI package and testing the functionality of your app again.

Remove the DLL from your installation. Also you might want to isolate the DLL using Application Isolation in Wise or Application Isolation Wizard in AdminStudio.

Windows File Protection (WFP) prevents installations from overwriting core system files.
Check your DLLCACHE in the System32 folder; that is the location WFP files are located.

Hi dm 1!
Thank you for reply! The trouble isn't dll files, but the I8042prt.sys and mouclass.sys files, that the software tries to update!

Hi oofemioo!

The to files that make the error is "I8042prt.sys and mouuclass.sys. If i try to remove them from the package, i can install the MSI package, but then the Mouseware doesn't work properly!
Is there away that you can get pass the "WFP".???????

Let's isolate the problems in a logical and step-by-step fashion

1. Check the version nos of the files contained in your app
2 Check the version on ur operating system
3. . Install vendors application again (without packaging)
4. Look for those files in ur system32 folder; Was the version changed to the one installed by ur app?
5 If there is a version change, I think u might have to Isolate those Sys file by moving them into the location of ur executable.
6. With 5 above; you do have to thoroughly test your application to ensure it works as desired and required.

Hi Bkr,

Also ensure the other files that are being installed to SYSTEM32 folder are not WF protected. You can check for WFP files in SYSTEM32\DLLCACHE.

The problem might u experiencing might not be with the 2 files u have highlighted previously

I hate to say this but maybe MouseWare is not compatible with the OS version you are running. I got burnt a while back by deploying Windows 2000 SP2 and having a bunch of machines not bootable the next day because some business unit wanted better mice and the MouseWare driver did not support SP2. I8042prt.sys and mouuclass.sys are Microsoft driver files. If your MouseWare won't work with it I would be talking to Logitech.
