Curl Problem With Upgrade.

I am trying to upgrade from 4.4.2 to 4.4.2.SP2 on a Windows 2012 R2 Server running PHP 7.0.

When I try to do the upgrade I get the following error.

Validation issue

Validator "Restore" returned fail status

			File
	


	
		
			Unable to prepare restore script. 

We have change the format of the file name already.

I have also made changes the permissions as I have found in other thread here.

I put in a Ticket and the only thing CS-Cart could tell me that it is a problem with cURL.

and that the Test they did showed an empty response. When I ask how to resolve this issue. They could not help me and I have no idea on where to start.

Does anyone have any suggestions that would help resolve this issue.

Thank you

Search forum for validation issue. If i remember correct there were windows dedicated issue where some symbos had to be replaced for some php file

Thanks Darius we had already made that change in a past upgrade and the file is still the same.

Did you try to inform hosting administrator about this issue?
