I am running Windows 10 Pro [Build 10240] and upon logging in tonight I find I am unable to install an MSI file as
The system administrator has set policies to prevent this installation only, I do not recall doing this, at all.
So I did a little digging and found this post, pretty cool. The best solution on this post was to run the install from an elevated command prompt, so I ran the following command:
msiexec /i example.msi
This resulted in the same outcome. Using the
/a switch also did not help me. So I did more digging and found a "fantastic" Microsoft post here. It applies to Windows 7, so I guess that's why the key does not exist on Windows 10 - the solution was to set
REG_DWORD = 0 in the
So, square 1. Another solution is to set UAC to never notify...isn't this default on a home system? Ran though and double checked it was set to never notify, rebooted, no change.
I wept for hours until I found another option. The next solution I found was to edit the Local Security Policy for
Software Restriction Policies. I messed around in here and could not isolate where to add the entry. I added a new hash for
%userprofile%\Downloads\ to allow all users to execute file types and ensure MSI was in the list.
I have ensured that my Anti-Virus is not blocking the registry changes, disabled all shields and re-attempted to no luck. I am now performing a full system scan to see if there are any threats on my PC. Long shot, but worth it.
Whilst that is running, I have made a new local account on the PC and ensured it admin rights. I've ran
mmc and ensured it in the
Local User and Group
Administrators group. Once the scan is done I plan on logging out, and attempting to install. I doubt this a user restricted issue but want to rule it out as an issue.
Next I ran
gpresult /h report.html and have a quick look to see if I had messed up GPO (I do set local GPO) and all looked well; just my standard disable of gadgets/Cortana etc.
Next I ran
sfc.exe /scannow and found no issues here. Frustrated, I went and edited the following values in Local Group Policy:
Computer Configuration > Administrative Templates > Windows Components > Windows Installer with the following:
Install with Elevated privileges set to enable.
Turn off Windows Installer set to disabled.
Same option with User Configuration. The last step is I have redownloaded the MSI and validated it not corrupt (works on Win8 VM). Any assistance would be appreciated.
