Why I can't install anything on my PC?

[kevin12haha]

Hello, my problem is when I've downloaded something from the internet, and I want to install it on my PC it gives the following error: "Another installation is in progress. You must complete that installation before continuing this one." Do you guys can help me?

Thanks in advantage.

Did this just happen on one occasion, or is this happening every single time you try to install something, even if the computer has just been turned on?

everytime when I want to download something.

Failed download

Most likely will turn out to be a program you installed recently, either failed to install correctly, or it was stopped part way through.
If you know what that was try uninstalling it.
Most effective program to do that would be 'Revo uninstaller', (free).
If you can't remember which program failed to install, try using 'CCleaner', use both the 'Cleaner' and 'Registry' options.
You might have both of those programs installed on your system, but as you can't download them, and do need to, you can install a portable version of both 'Revo' and 'CCleaner' onto a flash memory stick, and use from there. That assumes you have another pc or can borrow one for 5 minutes to download 2 programs.
Both programs are available from;-
