I am using Windows XP SP2 build 2600 with IE 8.0.6001.18720.
When the page is loaded it takes sometime to pull the cab file but when it should show a install prompt it displays below message in information bar.
"An add-on for this website failed to run. Check the security settings in Internet Explorer for potential conflicts."
I checked below points but no luck,
1. Added camera to Trusted site
2. Lowered the security setting for Trusted site to custom (Enabled options which allow installation/run the signed and unsigned activex)
3. Disable the Windows Firewall
The cab file is signed and it contains .inf file which launches the msi
[version] signature="$CHICAGO$" AdvancedINF=2.0 [Setup Hooks] hook1=hook1 [hook1] run=msiexec.exe /i "%EXTRACT_DIR%\myactivex.msi" /norestart
The currently logged in user is the Administrator and belongs to Administrators group on the machine.
If the same page I access from other machine having Win 7/8.1 IE 9/11 it properly installs the activex. Also it is installing when I try with Win XP SP3 IE 8.0.6001.18720.
I have checked almost everything I know but no luck.
I appreciate your guidance in resolving this.
