File Upload Field Security Issue

We have form that uses the file upload field to upload doc/docx/pdf files. When someone uploads a new file, we can not access the uploaded file from the entries screen in Gravity Forms. We get a 500 - Internal Server error. Upon checking the file system permissions for the uploaded files, the files are not inheriting all the folder permissions specified. When using process monitor, I see the IIS APPOOL\WordPress user is trying to access the uploaded file, with an access denied. The IIS_IUSRS group has read/execute/list folder contents/read permission on the uploads folder - but the file did not inherit this permission. This seems to have started when we applied the gravity forms 1.6.3.3.2 update as uploads prior to this update do not have the incorrect permissions. I have also applied the most recent update version 1.6.4.1.1 and it has the same issue. How can I correct this?

OK - found the issue. I updated PHP version when I updated the Gravity forms last month. The upload_tmp_dir had reverted back to the wrong path. Uploads are sent to temp and then moved to the correct folder. The move operation moves the permissions from the temp folder, instead of inheriting the parent folder permissions. Here is a wordpress post talking about this:

Thanks for now.
