Lot may time i come acorss a error MSG(Unable to silently launch embedded setup(27091)) while installing software which looks unresolved sometimes it gets fixed by changing a package however most of the times its bogs me down
i researched in many verticals but nothing gives me insight about the error.

it can be any software package not a particular one.

Short, practical add-on for : that exact message — "Unable to silently launch embedded setup (27091)" — is most often coming from a wrapped installer (an InstallShield Suite / Advanced UI style setup) that extracts one or more embedded installers and then tries to launch them in silent mode. If one embedded installer either requires interaction, uses a different silent switch, or fails to extract/run under the current account/context, the suite aborts with that 27091 message. The InstallShield docs show the suite launcher has its own logging/staging switches and that package-level silent command lines are separate from the suite's UI switches. (docs.revenera.com)

Quick troubleshooting workflow to identify the failing piece and fix it:

Run the suite with setup logging so you can see which embedded package fails, then extract the embedded packages and run the failing one directly. Example commands (use a temp folder you control):

Setup.exe /debuglog"C:\Temp\SetupExe.log"   (creates setupexe debug log)
Setup.exe /log"C:\Temp\PackageLogs"         (creates package logs)
Setup.exe /stage_only ISRootStagePath="C:\Temp\Stage"   (extracts embedded packages)

After staging, inspect C:\Temp\Stage for .msi or .exe files and run that embedded installer directly (MSIs can be tested silently and logged):

msiexec /i "C:\Temp\Stage\embedded.msi" /qn /L*v "C:\Temp\embedded_msi.log"

If the embedded .exe is non-MSI, look up its vendor silent switches (they vary) or run it interactively to capture prompts. These steps come from InstallShield guidance and real-world reports where staging/logging exposed the problematic embedded package. (docs.revenera.com)

Notes/tips: because you and others tried OS checks and malware scans (, ), that baseline troubleshooting is fine — but this error pattern points at the installer wrapper rather than core disk corruption. If you’re deploying via SCCM or as the SYSTEM account, stage first or run interactively for diagnosis — suite installers sometimes fail when run as SYSTEM because they try to download or write to a user-profile temp path; staging avoids that. If the vendor can supply an MSI or a documented silent switch for each embedded component, that’s the most reliable fix. (stackoverflow.com)

Hi and welcome to DaniWeb

A silly question...
When you got this error, are you still able to install a program successfully?

this may seem weird but did your computer have any recent virus attacks?

Nope the software doesnt get installed

Okay... which software you were trying to install when you have this problem? and which software that you manage to install without this error?

You can listed out the programs so I can find out which software that might conflict or it's within windows itself.

Call up Mircosoft? Are there any other microsoft experts living near you. Maybe you can ask them to have a look at your problem. I have never encountered this problem before so can't offer much help. Sorry about that.

sfc /scannow

You'll need an original Windows setup cd/dvd for it to run properly.
Usually this will correct any problem related to Windows program but not always so don't get high hope for this...

i think its not an issue with OS i think it could be an issue with the package.
