Exception in Install4j when creating an 32 bit Installer with bundled JRE - install4j

Question

Using Apache ANT I create a JRE bundle of a 32 bit JRE 1.8.202 using createbundle.exe:
<property name="CREATEBUNDLE" value="${install4j.path}/bin/createbundle.exe" />
<exec executable="${CREATEBUNDLE}">
<arg value="-o" />
<arg value="${install4jJREBundleDir}/${CURRENT_JRE_NAME}/" />
<!-- input -->
<arg value="${unzippedJREDirectory}/${JREDirName}/" />
</exec>
<!-- Get filename of created JRE Bundle -->
<fileset id="contents" dir="${install4jJREBundleDir}/${CURRENT_JRE_NAME}/" includes="*.tar.gz" />
<pathconvert property="INSTALL4J_JREBUNDLE" refid="contents" />
Using this bundle I try to create a 32 bit installer for my application:
<target name="installer.internal">
<install4j projectfile="${i4jprojectfile}" verbose="true" mediatypes="${i4jmediatypes}" destination="${dist}" >
<vmParameter value="-Dinstall4j.timestampUrl=${INSTALL4J_TIMESTAMP_URL}"/>
<variable name="BUILD_VERSION" value="${BUILD_VERSION}" />
<variable name="SOFTWARE_VERSION" value="${SOFTWARE_VERSION}" />
<variable name="PLATFORM_DETAIL_STRING" value="${PLATFORM_DETAIL_STRING}" />
<variable name="INSTALL4J_JREBUNDLE" value="${INSTALL4J_JREBUNDLE}" />
</install4j>
</target>
The following error is thrown when creating the installer:
350 [install4j] com.exe4j.a.d: Cannot bundle a 64-bit JRE with a 32-bit media file.

366 [install4j] install4j: compilation failed. Reason: Cannot bundle a 64-bit JRE with a 32-bit media file.
The JRE in the bundle is 32 bit, so the error doesn't really make sense.
Edit: I tried using install4j v7.0.18 and Install4j8.

Answer 1

The architecture is determined from the absolute path of the bundle file. Our bundle file resides in a folder called 'c:\src\Windows10_x64...' Because of the 'x64' in the path ('Windows10_x64') Install4j thought the bundle is 64 bit.
Edit: The solution was to use a relative path for the bundle file omitting the 'Windows10_x64' folder.
