Problem with upgrades to newer versions - reverts to prior versions without reas

[gisone]

I am running v0.21.1  after updating from version 0.17.

Twice in the past month v0.21.1 disappears and v0.17 begins running again (note the "unknown rules ..." message appearing which doesn't when v0.21.1 is running.) I reinstall v0.21.1 each time.

Why is v0.21.1 being replaced with my old v0.17 install? This is a Windows 10 installation. Thank you!

Do you have other software installed like deep freeze that could revert back to its original state every time you restart the PC?

If not then you might do wrong when installing the latest version, make sure that you close the Bitcoin core 0.17 and completely shut it down before you proceed to install the latest version.

If you did that already but it still downgraded to 0.17 there might be a system error from your PC that could revert back Bitcoin core to the old version.

Did you uninstall 17 and then install 21 or just install 21?
At a guess one is the 32 bit version which would wind up by default in C:\Program Files (x86) and the other is the 64 bit version which would be installed in C:\Program Files

So they can both be in their default location at the same time without overwriting each other.

First of all, open Control Panel and check list of installed application. If Bitcoin Core is listed twice with different version, you should remove the old one and make sure the new one automatically run during startup.

Maybe the old version is still inside on your pc, this is just my suggestion to clean your pc using : windows+r > cmd > and  cleanmgr

then windows+r > %temp% > deleted all cache , then windows+r > temp > deleted all cache

are you tick this?



and make sure your application was updated for the newest version, look at the control panel

How are you installing 0.21.1? Which file did you download from bitcoincore.org?

Did you download the "exe": https://bitcoincore.org/bin/bitcoin-core-0.21.1/bitcoin-0.21.1-win64-setup-unsigned.exe
or did you download the "zip": https://bitcoincore.org/bin/bitcoin-core-0.21.1/bitcoin-0.21.1-win64.zip

If you downloaded the .exe, then it should have "installed" 0.21.1 into the default location (C:\Program Files\Bitcoin) overwriting any previous version. If you downloaded the .zip and extracted it, it will just run from the directory where you extracted it... any existing shortcuts in the Start menu will likely continue to point at the "old" version in the default installation location.

That is to say, if you "installed" 0.17 using an .exe and it is in "C:\Program Files\Bitcoin"... if you download the 0.21 .zip file, and it is in C:\Users\YOURUSERNAME\Downloads\bitcoin-0.21.1-win64 and you run it from there... then 0.21 will open... but if you use the Start menu shortcut, it will likely start up version 0.17 instead!


As someone else already mentioned, there is also a possibility that something is "broken" with your Windows 10 install, and it is automatically restoring a previous "Restore Point" from before 0.21 was installed.

If this seems to happen overnight, it might be caused by an automatic windows update that is restarting your PC, encountering an issue and then restoring.
