A colleague has installed Adobe Acrobat 5.0 onto a new PC whose operating system is WinXP Pro SP2 without other applications. The Adobe Acrobat 5.0 application and the Paper Capture plug-in undertakes OCR without complaint. Then other applications were installed and the Paper Capture plug-in opened, but refused to OCR. Its been suggested that a dynamic link library (dll) has become corrupted or taken over by another application. Does anyone know how to get the dll that will allow Acrobat 5.0 to co-exist with other the other applications ?
