Nadya,

I've PDFWriter 5.0 installed on my PC and there is PDFWriter item with value 1 under HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Acrobat\5.0\Uninstall registry key. I think you can check for it to determine if PDFWriter 5.0 is installed. Using Rick's registry class

#DEFINE HKEY_LOCAL_MACHINE  2147483646
oReg = NEWOBJECT("Registry", "Registry.prg")
lcRegKey = "SOFTWARE\Adobe\Acrobat\5.0\Uninstall"
lnValue = oReg.ReadRegistryInt(HKEY_LOCAL_MACHINE,lcRegKey, "PDFWriter")
IF NOT ISNULL(lnValue) AND lnValue = 1
   * PDFWriter 5.0 is installed
ELSE
   * Assume that PDFWriter 4.0 is installed
ENDIF

>Most computers in our office have Adobe Acrobat Writer 4 installed. My manager's computer has Adobe 5. I was trying to use wwPDF class from west-wind.com wwPDF50 doesn't work on my machine (with Adobe 4 installed) and wwPDF40 refers to IsWinNT function, which is not included into the wwPDF archive. In any case, I need to know, which Adobe version is installed to use the correct class.
