An error occured during installation

hello PrestaShop Tips - PrestaShop 1.5 RC2 - An error occured during installation It seems the package I downloaded is not a completed one. Maybe the original files was not good. I downloaded another package 2 days later. that one was working properly. So if you encounter the same issue, I strongly suggest you to download the package again. PrestaShop team released PrestaShop 1.5.0.15, also known as RC2(Release candidate 2). It is a good news because that means we will finally get the final release of PrestaShop 1.5 soon. So I tried to install this version to make test. but there was a few issue when I tried to install this PrestaShop RC2. The first issue I encountered was that the package was corrupted, I guess there was some trouble on PrestaShop site, there are forum members reported the same issue. Fortunately the issue now has been fixed and we can download it now. The issue After I download the PrestaShop 1.5 RC package, and tried to install it, I chose all default selections and got following error when progress bar displayed 38% "" An error occured during installation... You can use the links on the left column to go back to the previous steps, or restart the installation process by clicking here. "" Will be discussed before starting the project What are the sites that offer the service i attach photo also thanks
