Backup Exec 12.5 install issues (error 1719: Windows Installer Service)
I was attempting to install Backup Exec 12.5 onto a Windows 2008 r2 server but the setup would fail with the following error:
Error 1719. The Windows Installer Service could not be accessed.
This can occur if the Windows Installer is not correctly installed.
Contact your support personnel for assistance.
Investigating/trying the plethora of results found via Google, I finally found the answer in the NetBackup forum on this support site:
User Christor discovered that "Windows Update for Windows (KB2670838)" was the culprit causing the error for his NetBackup install. I removed it from my server as well, rebooted, and was finally able to install Backup Exec.
I'm posting this under the Backup Exec forum so others can find the solution quicker than I did.
Note: I've since discovered we were licensed for 2012; I'll probaby reinstall the update to see if it's compatible.
