Item #25 - 64 bit /32 bit java [Opened]

I'm using Areca and Areca VSS in a 64 bit Windows environment. I have installed bot the 32 and the 64 bit version of java. When I use the program in the command line mode I get this error:

I tried every combination:

arecavss64+areca64
arecavss32+areca64...

Can you help me?

Hi

As said in the error message, you have to install 32 bit java runtime environment on your machine (and then use 32 bit Areca / ArecaVSS)

Best regards

I have a 32bit JRE and a 64bit JDK on my 64-bit machine.

Can we not have an environment variable (say Areca_Java_Home) so that users can have both 32- and 64-bit VMs without clashes? Or is there a way (in the areca config) to force it to use a particular VM?
