Horizon agent 7.13 fails install on Windows 7

RachelW — Tue, 08 Jun 2021 20:47:30 GMT

Hello,

We recently successfully upgraded our Horizon connection servers to 7.13 (from 7.8). However, I am having difficulty getting the 7.13 agent installed on my windows 7 golden image. I have successfully completed this on my Windows 10 image.

The install progresses along and all of a sudden it says "rolling back" and the green progress bar goes backwards.

We are running Windows 7 Enterprise SP1 64-bit.

Has anyone else had this issue?

Please check whether an installation log file exists with details regarding the failed installation.

Yes it does. Shall I post the entire log?

If you can't find out what may be causing the issue, then yes, please post the complete log file (unless it contains data that you don't want to disclose).
Please do not paste the log, but compress/zip the log file, and attach the .zip archive to your next reply.

According to the log file "Did not find QFE hotfix matching KB2685813" there's an issue with this Hotfix.
Either it's not properly installed, or it cannot be detected as already installed.

I can't tell you for sure how to fix this, but what you may try (after taking a snapshot) is to download the hostfix from https://www.catalog.update.microsoft.com/Search.aspx?q=Windows%207%20x64%20KB2685813 and install it manually. If it tells you that it's already installed, try uninstalling it. Make sure that you reboot the VM after installing/uninstalling the Hotfix, then try to install the Horizon Agent again.

I did see that error, downloaded the hotfix matching KB265813 and attempted the install. I received a message "This update was not applicable to your computer". I then looked for the update under Windows Update --> Review Update History and do not see KB2685813.

Just a guess, but maybe worth a try:

create a new directory, e.g. "C:\temp\KB-Hotfix"
copy the "windows6.1-kb2685813-x64_22a969bada171678b0936bb320e6a7778e8adc07.msu" to this directory
open an elevated command prompt (run as Administrator)
extract the msu:
expand -F:* C:\temp\KB-Hotfix\windows6.1-kb2685813-x64_22a969bada171678b0936bb320e6a7778e8adc07.msu C:\temp\KB-Hotfix
install the extracted cab:
dism.exe /online /add-package /packagepath:C:\temp\KB-Hotfix\Windows6.1-KB2685813-x64.cab
reboot the VM, and try to install the Horizon Agent

If this doesn't help run sfc /scannow to see whether it finds issues.

I followed your instructions to extract the msu which was successful and then attempted to install the extracted cab. Received the message below:

From what I found on the Internet, this error could be related to a stopped service.
Did you check the C:\Windows\Logs\DISM\dism.log for hints related to the error message yet.

The only thing I could see that was an error was "unable to create sessionID". Log attached.

What I found on the Internet is that people with similar issues had the "Windows Modules Installer" services set to "Disabled". Please enable the service (i.e. set it to e.g. "Manual") any try the installation again.
