uninistalled, cleaned registry, disabled virus checker, and dpp as well as eos lens reg tool loads, and then at the end NR without any explanation.

Windows 7 is not supported, and neither are the Windows 10 upgrades.  You need a new computer.  Microsoft dropped support for Windows years ago.

According to Canon USA support, 4.12.20 will work with Windows 7 64 bit as long as Microsoft Net framework 4.7.1 is installed.

Even the most recent release (4.13.10) will work with Windows 8.1 in addition to earlier versions of Win 10.

Not that Win 10 itself works that well...

The most recent version listed for Windows 7 that I see is DPP 4.11.

Yes, this was all working at one time, but it must have gotten corrupted, and I tried to re-install after trying to uninistall (unsuccessfully). and it will not install.

Greetings,

It will not hurt to try this:

Fix problems that block programs from being installed or removed (microsoft.com)

Similar to Revo and CCCleaner, but made by microsoft for windows 7,  8 and 10.

I'm with the others.  Windows 7 is EOL, and unless you have some compelling business purpose for 7 and are paying MS for support (translation) unwise business investment...  it should be abandoned.

MS is still allowing free upgrade to 10 using your W7 or W8 product keys...  (5 yrs later) so there is no reason not to install 10.  If your hardware won't support 10, it shouldn't be considered or used for post production in the first place.

Interesting.  When I select Windows 7 as the OS, the most recent version listed is DPP 4.11.0

Interesting.  The results are mutually contradictory.

I appreciate all you have offered, I just found out through my computer specialist, that my operating sytem need a full "repair" as there is something wrong which needs to be fixed. I got a hint, when I tried to download Picture Style editor and it did the same thing. I will let you know the outcome when my computer is back to it's regular self. Thanks again

Do NOT allow them to an OS upgrade of any kind.  Canon software is not compatible with an upgraded OS.  An upgraded OS is pretty harmless to applications that only process data, like a spreadsheet or a word processor.  But, an upgraded OS can potentially wreak havoc with apps that interact with the hardware, like USB ports and graphics.
