XP/2003 Windows Installer 4.5 differential patching problem

Hello,

I've encountered a problem regarding the Windows Installer program. I am using one of the popular install wizard programs, which uses the MSI installation engine. It provides the differential patching capabilities, which is of course supported by the Windows Installer.

However, I've encountered a problem while trying to apply patch on WinXP (SP3) and 2003 (SP2).

I get the 1328 Windows Installer Error:

"Error applying patch to file [dll_name] It has probably been updated by other means, and can no longer be modified by this patch. For more information, contact your patch vendor. [Abort/Retry/Ignore]"

The dll_name is my dll file, and this error occurs only with this particular file.

It has a bit over 20 MB of size, and the Total Commander plugin to compare files by content shows about 2,800 byte differences.

I've found in the depths of Internet that older versions of MSI had problems with large files with many changes in them, however I haven't been able to find any updates or hotfixes for XP to resolve this issue and make my patch work.

The only hotfix I have found was the : WindowsServer2003-KB983280-x86-ENU.exe for Windows 2003 Server, but it didn't make the patch work.

I have no more further ideas on how to resolve this issue and I would be glad to receive any help, which could lead to making this file patch properly.

You can download different versions of the Installer. Just search for the version that you want.

Some viruses overwrite that dll with an OLDER version, which messes up all backup operations. The install a PRE-SP3 version.

dglienna, thank You for Your answer.

However I've tried nearly all available versions of Windows Installer for Win XP and none of them helps with this issue.

Virus changes are also ruled out, cause the computer we have XP on in "net-free" with a clean WinXP SP3 installation on it.

I've used these. Be careful with SP2, as you have to remove SP3, which isn't always possible....

Oops. 7mb is too big to post.
