Title: Pelles C and Windows Defender smart screen
Post by: italofutura on April 14, 2026, 08:22:10 AM
Hi,

I tried to install Pelles C on my employer provided Windows 11 laptop. I do not have admin rights on this laptop.

when I try to install Pelles C a smart screen  appears, but due to lack of administrator privileges, I cannot proceed.

Other software works. Is it because Pelles C binaries are not signed? If yes, why?

Just install Pelles C to another PC and pack folder and use it other PC.
Pelles C is portable and works from USB-stick.
Sometimes have to adjust settings for INCLUDE and LIB folders.

Not a bad suggestion at all.

Normally for OpenWatcom V2, I decompress the executable with 7-zip. This is not possible with PellesC, but the principle is the same.

I will follow your solution.

Thank you.

Just in the rare case Timo's suggestion does not work - 

If you are still having issues you might try to unblock it first and then install to a folder other than Program Files xxx.  To unblock when downloading from the internet use the properties dialog see image.  If you can't unblock on the chief's laptop then download the setup on your laptop then unblock it and put on a USB.  Then try a standard install, or install to a 'user' folder.

Hi  italofutura,

Timo's suggestion is nice, Pelles C can work like a portable application. Do you have any chances to move temporarily your account to the Administrators group?
