Ppt to WMV requires high software, and the channels and specifications should be consistent. In addition, you are a cracked version, and cracking does not mean that you can support updates. Personally, I suggest that you download a cracked version of the hard disk and reinstall it. Don't worry about why some can be converted and some can't. Your fundamental task is to solve the PPT problem.

Ps:= = Software, as long as it is not genuine, there is no need to buy a disc.
