Mario,

"I have LOTS of 720p movies... was looking for an app to reduce this size. H.265 can reduce it by at least 35% with same quality."

FWIW... Because of generational loss, it's not gonna happen -- whenever you (re)encode video you will have some quality loss, so while you can get smaller files, their quality will be less than what you started with. How much quality you'll lose varies, depending on things like the quality of the original, software & settings used etc., so re-encoding the 720p might work well enough for you, but test 1st because you will lose quality.

[What the pros try to do is start out with higher resolution video than what they'll wind up with, so when the video's re-encoded after editing & processing, the quality loss doesn't hurt so much.]

Before using H.265 you might also test playback on the devices where you'll want to watch the video. H.264 & H.265 are very processing intensive, so Very often playback uses hardware assist -- since it's newer, not everything out there supports H.265 decoding, so it may or may not work, &/or it may not play at full quality.

Ken, your problem probably is not a corrupted file but another program blocking the installation. A strong possibility is that it is your antivirus program. Try disabling it temporarily if you have not already done so. Are you running any anti-ransom ware? If so, most likely you will need to temporarily disable it.

Another possibility is that your user does not have full administrator privileges. This can happen even if you granted your user full administrator privileges in the Windows "user account" application (located in Control Panel).

To get full administrator rights you can right-click on the setup file of the program that you wish to install and then click on "run as administrator", or similar wording, on the context menu that pops up. You can also locate the program "Take Ownership" on the web which can make a very safe change to your registry. The "Take Ownership" program will permanently let you take ownership of any file or folder that you wish. To use it, you right-click on the folder that you want to take ownership of and then left click on "take ownership" on the context menu that pops up.

I hope that one of these steps helps you install the program.

Jerry,

If it helps at all... Video-related software is often updated frequently because some of the code they might use, e.g. ffmpeg, is under constant development. The downside of more rapid development is that bugs & regressions can be more common [e.g. win10?], so if there's something you really rely on, it can be safest to hold onto the old version while you test the new.
