Yes I can do what I want. It's my children who are unable to use some software because they have a standard account. (yes, their account are already created).
"Run as Administrator" worked for "flv to avi converter" (thank you).
That trick doesn't works for some other programs like "Any video converter" or "Revo uninstaller"
I tried to give "Full control" rights to the standard users for the software .exe files (properties/security/(select the user)/Edit.../Full control).
But that didn't work.
When my son tryed to install "Revo uninstaller" in his standard account, he got the following message:
Error
You are not an administrator!
That doesn't look like a windows message. What do you think?
So I installed it using my account (admin). Then, my son got the same error message when I tried to run it.
It's the same for some programs.
Thank's if you have any other idea.
Have a nice evening.
