Hi all,

Was happily running electrum 3.3.4 on Windows 7 Professional. Last week I installed a couple of minor windows updates:

Windows Malicious Software Removal tool (KB8890830)
Monthly Quality rollup for windows (KB4503292)

Now I can't run electrum. I get the error :

Failed to execute script run_electrum

when I try and execute. I've installed the latest version (3.3.6 from electrum.org), but it's showing the same behaviour.

I've had a bit of a read round and I've already got KB2999226 that some posts suggest are required for this error.

Does anyone have any suggestions please as to how to resolve, before I take the more drastic step of restoring my system to the point prior to the windows update?

thanks for any advice you can give

Matt
