when running the jar (unpacked from installer) :

After adding the x64 platform in VisualStudio 2008, rebuilding and copying the 64bit lemur_jni.dll , I could run RetUI.jar without problems.

suggestion: Add x64 platform to the VisualStudio solution files, keep 32bit selected in default for the batch build. or add extra solution files.

however this solves the problem running RetUI.jar, it is not the solution for the Installer

Please run regedit.exe and inspect the key

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion

It should be "1.6"

That is the key that the installer checks to verify Java version 1.5 or greater, and should be set by the Java installer.

Did you install the JRE or the JDK or both? Did you install any 32-bit java versions?

Separately, the error message should have asked for 1.5.

We do not yet have a Windows 7 installation to test with.

reading wrong regkeys

The key does exist at this system:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime
Environment\CurrentVersion = "1.6"

I captured the install process and see it tries to open HKLM\Software\Wow6432Node\JavaSoft\Java Runtime Environment
resulting in "NAME NOT FOUND", just before the problem.
It seems that the installer does not look for the key you mentioned.

As you can see in the attached screenshot "You need version 1.4 or newer to run this program"

Yes, i also have the JDK installed @C:\Program Files\Java\jdk1.6.0_17

I didn't mean that you saw 1.5, rather that the error message itself is another bug.

I don't know enough about the 64-bit registry to explain why the installer was looking in HKLM\Software\Wow6432Node\JavaSoft\Java Runtime Environment

when the key specified in the installer source file (NullSoft Install System script) is indeed

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion

My Vista 64-bit system has both keys. It appears the Wow6432Node key is written for a 32-bit java install.

I apologize for the inconvenience. The next release's installer will omit the java version test, as 1.5 is plenty old enough for most users to have it or higher.

The only issue to be compatible with 64bit that needs to be solved is the lemur_jni.dll, this needs to be 64bit to run some lemur jars on windows 7.

will continue this issue as a feature request proposing 64bit installer:
