Problems when java is not found

Dear Sir,

I have found no place to report this problem except the “Post Idea” 1) CPN Version 4.0, Windows 8 64x, Open the program→ new net. Error Message: Beta Execution aborted: Stop is called. Error during dump: access violation. I expect to show a new net to start design a CN.

In the dump there is a path does not exists in my computer which is:

C:/cpn2000/document/ml/
dump:
eta execution aborted: Stop is called.

Stop message:

"*** Exception processing
ProcessManager exception. Error id: No such file or directory
Failed to start process: java"

I had the same error message, when opening a new net. I upgraded Java to the latest version(7u40). The x64 version still does not work, but when i am using the x86 version the problem is solved.

CPN Tools: 4.0 OS: Win 7 x64

Planned

This is caused by the tool being unable to find java. It seems to be a problem with Windows 64 bit and some other cases.

The tool should handle this nicer.

I had the same problem (CPNTools 4.0, Win7 64bit). Installation of 32bit Java solved the problem.

Same here with CPNTools 4.0 and Win 8.1 x64. Maybe you could consider publishing a 64bit version which supports 64bit Java in the future?

Hi

I have a similar problem when i want to install CPNTools 4.0(win7 64bit). This error is:” The installer could not fined a valid java™ on this machin.” How do i resolve this problem?

Thanks.

I had the same problem. Just add java.exe path to environment variable PATH.

Hi

I have a similar problem, when i would like open an existing net or create a new net.

“WARNING: Coluld not open/create prefs root nood Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreatekeyEx(…) returned error code 5.

#Beta execution aborted: Access violation. #Error during dump: Unexpected Signal. Aborting.”

The java version of 32 bit didn’t solve the problem.

I have a windows 7 64 bit and java version 7 update 60.

This is ridiculous because yesterday the CPN tools worked normally, but today the program is not working. Today Microsoft updated the windows….(KB2971850 and some others….)

What can I do? (ok, delete the version 64 bit, but I don’t like to do that…)

As mentioned, the problem is caused by lacking Java. Make sure to download and install a recent JRE/JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html (anything from 7 and up should work).

If you get the error, make sure to set your environment variables (varies with the version of Windows, so look that up; on Windows, select advanced system settings in Control panel and then Environment variables) so that JAVA_HOME points to the installation location (e.g., c:\Program Files\Java\jre8) and your PATH includes the bin directory under JAVA_HOME (in the example, it would have to include c:\Program Files\Java\jre8\bin).

Sometimes the installer sets this up correctly, sometimes not. It seems to be a problem especially with the 64 bit installer, but everything works with all combinations of architectures as long as the variables are set correctly.

I’ve added a section to the knowledge base detailing the problem (Can’t simulate model/Model stays orange). I’ll change the description to instead say that this should be detected and the user should be directed to a solution (it is not a problem in CPN Tools, it is a system problem, but CPN Tools should detect this instead of crashing).

just downloaded and had the same issue. Has anyone had another solution without deleting version 64 bit?
