I can´t get to compile my sketches

I use Win7 on my desktop, and every time I try to compile sketches, I get an error: collect2.exe:fatal error:cannot find 'ld'2. compilation terminated. Could you help me to solve this issue? I removed and reinstalling software but it is showed again. Thanks. :-[

Hey, try installing it again, and perhaps at another directory.
I am not using windows, however I believe this might help...

Let me know

Good luck.

Thanks Pixle. I tried what you recommend me but problem remains. In another topic in this forum I read may be is a problem with Avira antivirus, but I uninstalled it and same problem too. IDE 1.6.2, Avira reports virus TR/Crypt.XPACK.Gen several times - Installation & Troubleshooting - Arduino Forum
Thanks a lot and I´ll let you know when I´ll solve my issue.
My best regards.

Pixle, Let me tell you what I did for solve my problem.
I delete a folder name called Arduino15, inside C:\user\myname\appdata\roaming preferences.txt and everything looks good in this moment. I´m going to reinstalla antivirus and see what happend. Thanks.
