Installing software and getting "no write permission"

[LowBattery]

Hello! Thanks for reading this. I'm not especially computer literate, so please be patient. 🙂

I'm trying to install software on my MacBook. When I select my hard drive applications folder for installation, I get this message:

Error!
You do not have write permissions to the chosen installation destination.
Please choose a different location for installation.

I am on the admin account, so I don't know why it's giving me this.

In my weak understanding of computers, I thought perhaps I could repair disk permissions. After running that, I ended up with a gazillion errors, mostly related to my wireless printer, but the following, as well:

ACL found but not expected on "Applications/Utilities".
ACL found but not expected on "Applications".
ACL found but not expected on "Library".

I don't know if that relates or not. 😱

How can I give myself permission to install programs in my hard drive applications folder?
Where else should I install this program (and does it matter)?

Thank you so very much!

If you know iTunes, would you also take a look at this thread of mine, which didn't get much traffic?

Do a "get info" on the Applications directory. System and admin should have read and write access.

Thank you so much! System showed up, but not me. I added myself (sounds rather arrogant, yes?) and gave myself read and write permissions.

Thanks again!
