Hello,
I'm trying to portabilize an application for myself (ImageJ) and I would like to make it PAM compatible for installation (Iwante to create a paf.exe). i try to edit portableApps.com.installer.nsi, and then to compile it with NSIS. But i have this error :

Invalid command: MoreInfo::GetProductName
Error in script "Z:\PortableApps\PortableImageJ\Other\Source\PortableApps.comInstaller.nsi" on line 234 -- aborting creation process

Can you help me please ? I have poor programming level
