SOLVED -- BAD FILE DOWNLOADS
I can't get .72 to install either, installer just hangs at 0%. Thinking AV (Avast) because it usually insists on scanning a new EXE, I first excluded MC's folder in Program Files (x86), didn't help. I then disabled Avast, MC .72 still won't install.
Checked fairly worthless Windows Defender. Its live protection has long been disabled, so it supposedly only runs weekly to scan. Even when Defender runs, it is set to only Warn, not automatically Block. No evidence it is doing anything to MC install process.
I don't find any JR or MediaCenter programs or services running, so nothing obvious to force Stop.
And crazier, when MC installer starts, then hangs, clicking Cancel leads to confirming the cancel. When I click Yes (I want to cancel), it goes back to the installing dialog. Click Cancel again, same thing, it simply loops between Installing and asking for Cancel confirmation. Only Task Manager can stop it. But still, no successful installation.
I've never seen this problem in MC (or anything else that I recall).MC .70 and prior installed smoothly. I don't know of any changes on my PC *except* that Microsoft forced an update of something a couple of days ago.
And, my twin desktop has the same .72 installed without problem. (I run MC for video/photos on one PC, MC for audio on a twin PC.) It is set up exactly the same, with Avast, etc. No trouble with MC. I'm puzzled.
Restart of Windows didn't help. Disable AV didn't help. Guess I'm stuck at MC .70 on one PC. Suggestions?
