Have Call Manager 4.1.3 sr4d based on Windows Server 2000 SP4,
Cisco IOS version is 2000.2.7.
Want to upgrade win OS to 2000.4.4a.
2.1. I've downloaded "win-OS-Upgrade-K9.2000-4-4a.exe".
2.2. Before its execution, I've disabled antivirus & CSA and all third party applications.
2.3. While executing, it extract files into 'C:\mcsosupg' for a few minutes.
2.4. While performing, it suddenly said "Error Executing Mcsosupg.exe" dialog box and aborted.
2.5. When I'm going into 'C:\Mcsosupg\' directory, I could find Mcsosupg.exe there, but it has zero lenght.
3.1. win-OS-Upgrade-K9.2000-4-4a-Readme.mht doesn't describe my problem.
As i see, Phase 1 hasn't even begun and accomplished
3.2. I can't find log file 'C:\Program Files\Common Files\Cisco\Logs\mscosupg.log'
Any suggestion would be greatly appreciated.
