PC of unknown origin requires software to be installed. System locks up while copying installation package from network server. Run Cleanup and SpyBot on system. Attempt to install Lotus Notes client, but receive prompt for Windows File Protection - Windows files must be installed for your installation to proceed. - Insert your Service Pack 4 CD now.

Since the CD isn't in my hand, I cancelled the prompt. Unfortunately for me, the Lotus Installation backed itself off and said it failed.

The Application Event Log had this to say:

The extended info above says this error is related to the installation package for Lotus Notes 6

After searching for this error online, I went looking for the file in question. I found this info on the system having trouble:

Directory of C:\WINNT\ServicePackFiles\i386

06/19/2003  12:05p             164,112 olepro32.dll

Using another Win2k box for reference, the file has the same date and size, but the time is a little different. It also has copies in:
C:\WinNT\System32
C:\WinNT\System32\dllcache

I copied the file to the System32 folder and discovered it magically appeared in the dllcache folder.

Kick off installation and it completes successfully!

Run into the same thing while loading Symantec Antivirus Corporate Editiion

This time, I just copied the comcat.dll file from C:\Winnt\ServicePackFiles\i386 to the C:\Winnt\System32 folder and tried again.

We may be looking at applying Service Pack 4 again in the near future, but for now everything is peachy.
