Error 500 now white screen

I try installing a module on suite crm and was getting error 500 timeout. I finally managed to get past that with the help of the hosing company but now when I install a module after accepting the license it goes to a white screen and never comes back and the module doesnt install. Occasionally I get a cannot copy a file to another folder error but that pretty sporadic. Mainly it just goes to a white screen no errors that I can find.

Its just when you install additional modules. running IIS and Sql server

Hi Kevin,

Sounds like a permission or PHP upload limit issue. See the SugarCRM Windows permission page for recommendations.
