Client install error Windows 10 1803

Question

Hi, 
 
 I am getting this error when trying to install the client installer via cmd. 
 
 Product: Sophos SafeGuard Client 8.10.0.323 -- Error 1935. An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.6195",publicKeyToken="1fc8b3b9a1e18e3b",processorArchitecture="amd64",type="win32"'. Please refer to Help and Support for more information. HRESULT: 0x80073715. assembly interface: IAssemblyCacheItem, function: Commit, component: {844EFBA7-1C24-93B2-A01F-C8B3B9A1E18E} 
 
 I have searched and a couple of proposed fixes 
 https://community.sophos.com/kb/en-us/124301 
 Was already on version 8.0.2 so on the back of that i upgraded my server to 8.10 and updated all the client installers, pre install and poa. 
 which didn't fix the issue 
 
 This suggest fix refers to windows 1709 which i do not have this option in the latest 1803 
 https://community.sophos.com/kb/en-us/128152 
 So wasn't able to try that. 
 
 I use had been using: MSIEXEC /i c:\SGN\SGNclient64.msi POACFG=c:\SGN\POACFG_8_10.xml With the latest client, then running the patch afterwards. Thought maybe the patch fixed the issue so tried running the patch but didn't work because it didn't detect the client to patch it so then i tried this: MSIEXEC /i c:\SGN\SGNclient64.msi PATCH=C:\SGN\SGN8005Patch1804_x64.msp POACFG=c:\SGN\POACFG_8_10.xml to install the client and patch at the same time. Different error altogether. 
 
 Any ideas?

Hi Kevin, JaffNSX,

Can you please help me with verbose logging of the MSI installer when you try to run it? You can use the following format while installing to generate a verbose log of the installation.

msiexec /i "<installer location\installer.msi>" /L*VX "<loglocation\logfile.txt>"

Please DM me the log file and I shall look into the same for you!

Also, from the first look, looks like you can try this fixit by Microsoft since the error seems to be the same.
