Planning an upgrade I've downloaded both the CCMUPGDAsstInstall.4-3-12.exe and CCMUPGDAsstInstall-4-3-10.exe files. Either file execution results in a Windows Installer message stating:
"Error opening installation log file. Verify that the specified log file location exists and is writable."
I am using Windows 7 x64 bit OS.
Anyone run into this problem, installing the CCM Upgrade Assistant?
Are you trying to install the Upgrade Assistant on your local desktop - you said you were using Windows 7 x64bit OS - so I'm assuming you might be. If so, that's the problem. The Upgrade Assistant is installed directly on the CCM (Windows) servers and when you run it, it verifies that the system is healthy prior to upgrade.

Here are a few details taken from the Upgrade Assistant Guide which you may find useful:-
Your server login account must have Administrative privileges to run the utility. You may log in to the server by using the Administrator username and password.
Before you begin the upgrade on the publisher database server, you must run the utility on all servers in the cluster. If any server fails the validation process, investigate and correct the problem(s) before you begin the upgrade on the publisher database server. After you correct the problem(s), run the utility again before you upgrade.
You can run the utility on only one server at a time.
Cisco strongly recommends that you run this utility during a scheduled, maintenance window.
