After redownloading the game yesterday, today I tried to update to the latest nightly as usually, but the Java updater failed.
Running it either results in 'State: FAIL' after trying to download the hash manifest for less than a second, or the following error:
Exception occured: JAVA.NIO.FILE.ACCESSDENIEDEXCEPTION: C:\WINDOWS\SYSTEM32\SIMUTRANS EXTENDED.HASH.TMP
('State: FAIL' appears when double-clicking to run; the error message appears when using 'Choose another app' and then navigating to javaw.exe to open with that)
I am not sure why the updater is trying to access a file in SYSTEM32 or exactly what's causing it to fail; running it as admin did not resolve the issue. Tested on both JDK 14.0.2 and JDK 15.0.1; Windows version 10.0.19041 Build 19041, 64-bits; re-downloaded the updater from the forum (even though it appears to be the same version as mine) gave the same issue.
This doesn't affect the game itself but is still slightly inconvenient, has anyone else had similar issues and/or found workarounds?
