When installing Avaya IP Office Voicemail Pro 9.13.0, I came across this error, 1327 Invalid Drive:<driver letter of problem drive> and was unable to install voicemail pro.
Searching google suggested that a change is made to the registry to resolve this issue for office installs, and some suggested disconnecting the drive and disabling automatic reconnect.
There is, however, an easier solution:
Step 1: Create the local voicemail user
Step 2: Log in as that user,
Step 3: Run your installation application again. It should now complete without error. If you are asked to restart the machine, you must log in using the local account to continue installation.
Step 4: Once the install is completed, you can continue to use your domain credentials.
I hope this saves you some time.
This problem is not really Avaya related, but an issue with Microsoft Windows, so this procedure may or may not work for you if you are trying to install some other application, but it’s worth a shot. Let me know if it worked for you…
