Automatic Updater Fails to Update

[dannyliux]

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?

I have had the same issue on linux.

Thank you for letting me know. I suspect that this is caused by the renaming of what was formerly Simutrans-Extended-64.exe to Simutrans-Extended.exe as the 32-bit builds for Windows were discontinued.

I do not know enough about how the automatic updater works to know exactly how this causes the problem. I will try to create a copy of the Simutrans-Extended.exe file called Simutrans-Extended-64.exe and see whether that works.

Following today's (20-12-21) nightly rebuild, the Nightly Updater partially works on Windows. It appears to correctly update all files except one. It deletes Simutrans-Extended-64.exe and does not replace it.

Is this different to the previous behaviour?

Yes. Up to very roughly a week ago, the Nightly Updater worked perfectly. Yesterday (and for at least a couple of days previously) I had similar symptoms to those described by dannyliux: the Updater reporting "FAILED" or various Java errors on the command line.
