Can't install CIS Premium 2025

Greetings Baltazar1,

I got that error message while trying to install CIS2025 on Windows 8 which is not supported…

Did you upgrade to win10 or its a direct install of win10?

Do you sometimes empty those directories:
Windows button + r: temp
Windows button + r: %temp%
Windows button + r: prefetch

Have you tried settings your DNS for COMODO’s one before looking for Windows updates?

  • Control Panel > Network and Sharing Center > Change adapter settings > right click your adapter then “Properties” > left click IPv4 then “Properties” > Use the following DNS server addresses:

8.26.56.26
8.20.247.20

Do you sometimes run:

  • CCleaner > Custom Clean > uncheck “Memory Dumps” and “Windows Log Files” > Analyze > Run Cleaner (might have to disable “Continue running background extensions and apps when Microsoft Edge is closed” and “Startup Boost” under Edge’s settings: Edge > three dots button (top right) > Settings)
  • CCleaner > Tools > Registry > scan for issues (run it multiple times until no errors are found)
  • Control Panel > Administrative Tools > Disk Cleanup > “Previous Windows installation” (if Windows was upgraded) + possibly “Device driver packages” (before running dism scans down below)
  • MRT: https://www.microsoft.com/en-ca/download/details.aspx?id=9905

  • Powershell: dism /online /cleanup-image /checkhealth
  • Powershell: dism /online /cleanup-image /scanhealth
  • Powershell: dism /online /cleanup-image /restorehealth (if issues detected with …/scanhealth above)
  • CMD: sfc /scannow

Greetings,

On a fresh win10 install, upon reaching the desktop for the first time after installing Windows, I immediately tried to install CIS 2025 and got the same error message as in the OP: “The installation does not support target platform”.

Windows + r: winver

…shows that its Windows 10 Version 1903 (OS Build 18362.30).

As others suggested in this thread, fully updating Windows might be the key to install CIS 2025 (for now).

P.S. After fully updating Windows 10 (to version 22H2 (OS Build 19045.4842)) I was able to install CIS 2025.

Hi Baltazar1,

Are you running any other security software other than CIS ?

Thanks
