I've a problem upgrading from Greenstone 2.71 to 2.74. I've running a
Greenstone 2.71 on a Windows XP SP2 machine for over a year. Now I tried
to install Greenstone 2.74. The installation breaks down with the
following message:

Errors occurred during the installation.
JVM not found

I reinstalled Java but nothing changed. Greenstone 2.71 now shows the same
message. What can I do?

Thanks a lot
