#394 v6.0.0 fails to startup on Win10

[Masanori Miyoshi]

Installed davmail v6.0.0 on Windows 10 but it fails to startup due to JRE not found.
v5.5.1 works without any problem.

C:\>java -version
java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)

Error message as attached.

Can confirm, on Win10 x64 Version 10.0.19043.1081 DavMail 6.0.0 in not starting - Java missing.
Just before 6.0.0 I was using 5.5.1 and there was no problem, just uninstalled 5.5.1 and installed 6.0.0 as usually made this way.
I even tried to check with Azul Zulu Builds, no change.

C:>java -version
openjdk version "16.0.1" 2021-04-20
OpenJDK Runtime Environment Zulu16.30+15-CA (build 16.0.1+9)
OpenJDK 64-Bit Server VM Zulu16.30+15-CA (build 16.0.1+9, mixed mode, sharing)

Small update: I installed 32bit Java and DavMail and that started right away and seems to be working fine.

I created davmail64.ini to specify the VM location:

vm.location=%JAVA_HOME%

and still got the following output:

The "standalone" zip seems to work though.

I can confirm this for Windows 7 64-bit as well. I have 32-bit and 64-bit Java 8.0.2910.10 installed. Re-installed 5.5.1-3299, which runs without problem.

[Mickael Guessant]

Regression probably related to changes introduced for standalone package:

ini.override=true
vm.location=./jre/bin/server/jvm.dll
vm.sysfirst=true

=> please try removing all those lines
=> to force vm.location you need path to jvm.dll, not JAVA_HOME

[Masanori Miyoshi]

The ini file is not created during install so I can't test if removing those lines works.
Pointing to the jvm.dll worked.

[Glenn Burson]

I re-installed version 6.0.0-3375 and created the file 'davmail64.ini' in DavMail's installation directory with the single line:

vm.location=C:\Program Files\Java\jre1.8.0_291\bin\server\jvm.dll

This worked. DavMail64 launches without error.

[Daniel Wróblewski]

Your method worked straight away.

[Carsten Hütter]

Can confirm that it works. Thank you!
