Failed to install savxp: uninstalling an older product failed.

Hi skyisbluescreen 

Would you please suggest what is the exact error it is showing under the events? 

Hello there,

I have updated the Event log in the post. All the machines show the below error :

Everything was normal in these devices Sophos was working fine perfectly. However there was 1903 installed they rebooted and boom Sophos AV service goes missing and other ones too.

Hoping someone from the community can help me through.

------------------------------------------------------------------

I have tried Support:Here is what happens

SDU Logs shared for impacted PC's

Request us back to re install

We Do, and Still same problem.

We Report back, they connect and run a PS SCRIPT or BATCH to remove Sophos, Still issue persists after re install

Request to Re Install the OS

-------------------------------------

We have this problem also for several Win10 machines. Solved by run update from Sophos Endpoint UI on "problematic" machines and by several restarts.

In "Sophos Central Console" are "device status" ok, but on some machines is the status Red - "you have to call IT .." (free translation from Czech language").

On fully updated machines and also on machines with some missing patches.

Hi Jiri Hadamek 

Devices with red health status on central, does it show any specific service stopped or any other detections? 

It haven´t service stopped. It simply haven´t service installed.

Now - after several restarts AND several "update NOW" from Sophos UI on PCs we have the following state:

In Sophos Control Central - OK

ALL Sophos services ARE running - OK

On workstation - Sophos show errors - see the attached pictures.

Hi Jiri Hadamek 

Could you please translate the error message shown in the Endpoint UI? Which service state is in the stopped state? 

Translated freely into English " Some services aren´t started. Call IT" But ALL services ARE running. (After several restart and reinstall from LOCAL Sophos UI)

Hi Jiri Hadamek 

Can you please click on About > Open Endpoint Self Help Tool > Services and check which services are not running? Do you see any components which are not installed? 

All services ARE running

and

ALL services ARE installed.

Yep, same here.

Console:

" Failed to install savxp: uninstalling an older product failed."

Log:

"WARN  Failed to install product E17FE03B-0501-4aaa-BC69-0129D965F311 10.8.7.1000."

Version agent: 10.8.6 VE3.78.5

Can you find (and attach) the install and uninstall logs of SAV in \windows\temp\ (if this is an AutoUpdate initiated install attempt) or under %temp% if you are performing an install with say the Sophos Central installer they would be under %temp%.

Seeing error 1612 on SAV uninstall and install logs. The uninstall process is looking for the MSI which is missing in this path: C:\WINDOWS\Installer\60e64.msi.

You can try uninstalling Sophos using the SophosZap tool, and then reinstall Sophos.

The install is finding a version of Sophos Anti-Virus installed (ProductCode - BEEB46C0-1983-4DF2-AD40-8C464842DF24) which appears to be broken:

2020-06-15 10:26:49 There is an incomplete SAV installation, forcing a Major Update to recover

It is then starting the uninstall of it:

2020-06-15 10:26:58 WARNING: SAV uninstall failed with error 1612

The issue is, the uninstall is failing with1612, which is ERROR_INSTALL_SOURCE_ABSENT.  So there is no cached MSI for the product code BEEB46C0-1983-4DF2-AD40-8C464842DF24.

The easiest thing at this point is probably to run SophosZap - https://community.sophos.com/products/endpoint-security-control/b/blog/posts/sophos-zap-is-now-available The alternative is trying to piece together a number of files from another computer.

Well yes, this method works. But it isn't good way to fix this issue :(
