I'd be happy to help you install the new version of HitPaw Video Converter for iPhone.

However, I noticed that the key provided is 'instal the new version for iphoneHitPaw Video Converter 3.1.3.5', but the text provided describes how to check system and hardware specs for Windows, which doesn't seem relevant to installing a software on an iPhone.

Could you please clarify what you mean by 'install the new version for iPhone'? Are you referring to installing HitPaw Video Converter on your iPhone, or perhaps converting videos to a format compatible with your iPhone?

Additionally, I noticed that there is no mention of downloading and installing software on an iPhone in the provided text. iPhones do not support installing software directly like computers do.

If you meant to ask about how to convert video formats for use on an iPhone, I can provide guidance on that as well. HitPaw Video Converter does offer features for converting videos to MP4 in HD quality and optimizing them for iPhone and iPad.

Please clarify your question so I can better assist you!
