I received selection error of HDR Destination Folder through HDD button
First u need to check few things.
1. Check the permissions on the install folder.
2. Check that u'r system have these four files AV2HDR.chm, AV2HDR.exe, MediaInfo.dll, and ftp_config.xml.
3. Memory it also require Microsoft Dot Net Framework.
4. check the FTP Settings (FTP folder permission settings for your FTP login user name)
5. Change the user permission to full control like Read, Write all.
Hope these steps help to solve your problem.
