Exchange Server 2013 Missing file on ISO install Error Code 1603

Question

Hi all,   a mystery needs solving any suggestions much appreciated:
We are trying to install Exchange Server 2013 on Windows 2012 server.
The ISO File being used is: SW_DVD9_Exchange_Svr_2013w_SP1_MultiLang_Std_Ent_MLF_X19-35118
All preparation and requisites in place.
During Stage 2 Copying files, we receive an error code 1603 and installation halts.
The error states:
Installing product F:\exchangeserver.msi failed. Fatal error during installation. Error code is 1603. Last error reported by the MSI package is 'Source file not found: F:\Setup\ServerRoles\ClientAccess\Owa\prem\version\resources\themes\base\0\microsoft.o365.controls.timeline.mouse.css.
 Verify that the file exists and that you can access it.'.
We have verified that the Path in the error is correct and exists BUT the file is not present within the 0 folder.
We have downloaded the ISO from our Action Pack resources twice and attempted 4 separate installations.
We have tried both Mailbox/Client Access  and Mailbox only installations.
The missing file: microsoft.o365.controls.timeline.mouse.css. Hopefully the only file misisng???
Any ideas anyone, could we source a different ISO or copy of the file or ?????
Many thanks in advance

Had the same issue with Exchange 2013 SP 1 Downloaded as an ISO from the Volume License Center, installing on a new Server 2012R2 STD box. I found the equivalent file in another ISO but discovered it was just an empty CSS file. So the easiest way is to not
bother trying to find the file but: 1) open notepad, 2) set save to "All Files", and 3) save an empty CSS file with that filename then place it in the directory indicated in the path given in the error. (Make sure it saves as
a CSS and not as a TXT.)
I reran the install and it completed without issue.
