Difficulty with updating Flash - gnb-6/22/17

Question

OS = Windows 7 - currently up to date.

Browser = Firefox 54.0 (32-bit)

Flash NAIPI = Ver 25.0.0.171 (current)

Whenever I am prompted to download the latest Flash update on my PC (in this case Version 26.0.0.131), the exe file successfully downloads. But when I attempt to install, I get nothing but a blank software loading window (see http://www.publicom-usa.com/misc/image1.jpg). Then, when I close this blank window, my computer automatically opens Internet Explorer (which is not my default browser) but nothing happens (http://www.publicom-usa.com/misc/image2.jpg).

However, usually a day or two later, my Avast Security Software Updater is able to download and update the latest Flash with no issues.

Since I'm tired of having to wait for Avast to do what should be a simple task, can someone tell me what I must do? FYI, I have Adobe Creative Suite (4) loaded to this machine. But I also have CS4 on my laptop, and do not experience this problem when updating Flash.

I'll try and check this forum daily and hope someone can explain what needs to be done. thanks.
