OpsCenter 7.5 Server Installation Issues on W2K8R2 - Error 1719 - Windows Installer Service
I am trying to install OpsCenter 7.5 Server, followed by the 7505 update, onto a W2K8R2 SP1 server. I have done this many times before, however I have not previously come accross this error.
I am running the BROWSER.EXE as administrator, which launches me into the install GUI screens. I select Installation, and then OpsCenter Server, complete the first few screens, select CUSTOM INSTALL and change my install locations to the D drive of the server. After selecting install I immediately get a pop-up box saying Error 1719 - The Windows Installer service could not be accessed etc. etc. As this is a single Master Server / Media Server installtion I am installing the OpsCenter onto the Master Server - however I have also tried on another W2K8R2 server and I get the same results.
I have trawled the various posts around this error, and checked that the Windows Installer Service is running, re-registered the msiexec dll (both system32 and syswow64) but to no avail. I have successfully installed Netbackup 7.5 and the 7505 update on this same server - no problems.
Any advice / suggestions ? Is this around a 32bit/64bit issue, and related to the syswow64 ? I am however confused as to why NBU iteslef installed with no issues but OpsCenter is not installing.
