[SOLVED] 64 bit and 32 bit issue in R and java integration

64 bit and 32 bit issue in R and java integration

I have used R 64 bit and 64 bit machine, but it still complains of 32 bit. Not sure why it is saying IA 32-bit platform

java.lang.UnsatisfiedLinkError: \statistics\R\sdk\library\rJava
\jri\x64\jri.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform

Solution

Tim, thank you for your clues. The issue was with my JDK was 32 bit, while OS was 64 bit and I had installed R with both 32 bit and 64 bit versions ticked during install.

The issue is gone, after uninstalling R and re-installing only 32 bit version of R. In short, when jdk is 32 bit use R 32 bit irrespective of OS
