Hi everybody, my first message on this forum...i appologise if the question has already been posted but it doesn't seem... First thanks Arno for your Obplacer family i often used until this problem... i had to resinstall my OS(Windows XP) 3 days ago. I had not made any bakup of my windows/system and system32 files cause the OS had numerous system errors... I had been using Obplacer 0.82 without problem before this reinstallation. After it, i couldn't launch Obplacer as the following message appears : "error system &H8007007E (-214704770). The specified module cannot be found" I installed then Obplacer 0.83. But i got he same message... I search on google about this error message; it was described as an error due to default Java. I installed Java J2RE 1.4 but it didn't solved my problem... Has somebody an idea, please?
