I am trying to install the latest patch (14.0.4a.413) onto Filemaker server 14 on windows server 2012 r2, but it isn't installing.
I have tried many different things but it always ends up resulting in and 'Windows Installer' window popping up and the install fails (image attached).
I have tried the following...
Uninstall and reinstall of filemaker 18.104.22.168 then installing patches/updates in order.
Got a complete version of Server 22.214.171.1242 (i.e. no need for earlier versions to be installed) then tried to install the patch.
Reinstalled Microsoft AAR and other items before a reinstall of Filemaker Server. Process I followed is here Manually Installing Microsoft Application Request Routing (ARR) for use with FileMaker Server for Windows | FileMaker
I have also tried all of this on different drives on the server too i.e. c and d drive.
The only thing that has come up in Event Viewer is error code 1603 and I have tried what it has suggested in there too with no luck.
I cannot find anything in the forums on a possible fix for this, does anyone have any idea what I can try next or if there is a fix.
