When running 32-bit TIBCO Installer on x64 platform, you may encounter this error TIBINS202504 INTERNAL ERROR: You do not have the required administrator privileges for the Install Wizard to proceed with installation. Then following window appears, which contains more useful information: java.lang.UnsatisfiedLinkError win32ppk.dll Can’t load IA 32-bit .dll on a AMD 64-bit platform.
To solve this problem, you have to run installer with 32-bit Java. There are two options: you can temporarily point JAVA_HOME system variable to 32-bit Java folder or run installer with -is:javahome parameter like in my example:
TIB_adswift-simple_5.8.0_win_x86.exe -is:javahome "C:\Program Files (x86)\Java\jre6"
